man this game is good. amazing soundtrack, satisfying and crunchy sound effects, and beautiful artwork. the story is incredibly confusing, yet intriguing. gameplay is incredible, with one of the smoothest time-stop mechanics in any video game i've ever played. the boss fights are great, and because it works the death mechanic into the story, boss fights specifically feel like you can predict the future. the game is certainly difficult, but it rarely feels unfair and i never got stuck on a specific room or boss for too long. npc dialogue is funny and adds another layer of immersion to each room, and it often references itself over time (rip strong terry).
hard mode however, is absolutely brutal and i still haven't beaten a run on it. (EDIT: i have beaten a hard mode run now) i've attempted a few speedruns but never got that far, so the only two achievements i'm missing are the gold speedrun one and the hard mode one. (no longer the hard mode one)
it's pretty short, but including speedruns and secrets you could certainly stretch out the playtime quite a bit.
absolutely recommended.

portal 2 is a great game.
soundtrack is nice, sound design is nice as well. artstyle and visual design is beautiful and really fits with the post-apocalyptic setting, even if it's entirely underground. the puzzles aren't too challenging, but they still are satisfying to figure out. the portal mechanics are nice and feel satisfying to use. the story is great and dialogue is some of the best in any video game ever imo, and the characters feel real as well.
the coop multiplayer is fun as well, but it lacks the story and interesting dialogue of the main campaign so it's not as fun for me.
amazing game.

in my opinion the best movement shooter ever made, massive depth to movement and combat. the soundtrack is amazing, and it really compliments the fast paced gameplay. artstyle is really nice and most of the levels look amazing even with the low poly graphics. you can even change your graphics to be so shit it's practically unplayable with the psx settings.
this game really shines in it's movement and gunplay. you have a slam, a slide, a walljump, a dash on ground and air, and a ground jump. these movement options can be used on their own as normal, or combined in different ways to gain crazy speed and mobility. in terms of weapons, at the time of review there are five guns, a pistol, shotgun, machine gun, railcannon, and rocket launcher. each of these have variations which add different abilities to each weapon. this includes a pistol variant that allows you to throw coins in the air and shoot them for an instant ricoshet into an enemies weak point, a railcannon variant that shoots a red explosion laser beam, and a rocket launcher variant that can freeze your rockets in midair. weapons can be used together in interesting ways, such as shooting multiple midair coins with a charged pistol shot to deal huge damage or shooting a launched shotgun grenade with the explosive railcannon to detonate a massive nuke that decimates everything around you. some of these weapons can also be used in conjunction with movement to give even more speed, like the explosive railcannon + grenade nuke can launch you massive distances under the right circumstances.
you have one arm to begin with, called the "feedbacker" which can be used to punch enemies and also parry attacks and projectiles. this can also be used to punch coins out of the air, which can hit enemies and stack damage for some very quick kills if you can consistently punch the same coin. it can also be used to punch your own shells out of your shotgun, which propells them much faster and causes them to explode on impact. you can collect two more arms as of this review, the "knuckleblaster", which has a much more powerful yet slower punch, and a shockwave that activates when holding down punch that can deflect projectiles and damage/launch smaller enemies. the last arm is a grapple hook that can pull yourself towards bigger enemies and reel smaller enemies in towards you. these all flow together to create some of the best fps gameplay i've ever seen. the game has a style meter, which encourages swapping and combining weapons, as well as moving fast and not getting hit. the style meter affects your end of level score, as well as reducing the amount of hard damage you take based off of how high your style is. the way you regain health is through absorbing blood from enemies, and that incentivizes up close combat as well. this all comes together to create one of the most fluid combat systems in any fps game i've ever played.
the end of level score system relies on three things. style, time, and kills. you can get between a d and an s in each of these catagories, based off of specific par numbers for every level. if you get an s rank in every catagory without dying once throughout the level, you can obtain a p rank for that level. if you get all p ranks for a specific act, you can unlock a "p door" which leads to a secret boss/level that is vastly harder than anything else in the game. these are where the game shines in terms of difficulty, and are some of my favorite levels in the game.
there are four difficulties at the time of this review, with two easy difficulties, one normal, and one hard. i did my playthrough on violent difficulty, (hard) and found it to not be too bad, so if you are decent at fps games than go with that, normal difficulty seemed pretty easy.
ive fully completed every level, every secret mission, and most secrets, as well as p ranking every level on violent difficulty except for the second p level, which ive p ranked on standard (normal). this game is in early access atm, which means that theres much more content being added, but it is easily worth the twenty bucks if you like movement shooters.
amazing game, ive sunk over 200 hours in it by now and damn is it fun

so many hundreds of hours wasted... i haven't gotten all achievements for this game because there's like six hundred but believe me i'll keep going.
some surprising depth to the systems and automation here, but nothing too crazy.
i played on browser some years back, found it on steam about a year ago and bought it for five bucks. only important thing the steam version adds is music, which is surprisingly good. it's composed by c418, the same guy who did the classic minecraft soundtrack, so honestly no wonder it slaps.
it's pretty fun lining up the combos to gain massive amounts of cookies, and theres even a prestige system which allows you to purchase upgrades in the afterlife to affect your next cookie playthrough.
pretty sick ass game, a little over 350 hours at the time of review.

great game. artwork and character animation is amazing, music is great too and sound design is nice as well. controls are responsive and the parry system is well designed. it's easily my favorite 2d shooter, but that's not really a genre i get into much so who knows. difficulty is nice and challenging yet fair, and the extra challenges like run and gun levels and mausoleums are fun as well. the run and gun levels do get a bit repetitive though, so i'm glad they went with a boss focused structure instead. the flying boss segments were a low point for me though, really felt like they were a step away from the fun platforming and more just like bullet hell asteroids gameplay.
really good game and worth the price

i did not fully complete this game, and by that i mean get all endings, but i did beat the game fully for the neutral ending. the soundtrack was nice and the story was interesting, but didnt captivate me in the same way it did many people apparently. gameplay is fine, nothing special, and the pixel artstyle isn't great by any standards. boss fights were cool, and some of the environments were pretty nice to walk around, but it's not as perfect to me as it is to other people. still, i can see that people love it, and good on them.
