Based on completing all content on Nightmare mode, including an ALL+ run. I've also beaten the Extra stage and all of the individual stages (except 9) on Chaos.

Excellent shmup that blends the fun parts of CAVE and Touhou with exquisite stage and boss design. The recharging hypers and bombs let you experience the power fantasy of mowing through swarms of enemies, but you can't just spam them; there's a carefully considered balance between resource management and dodging (both practiced and ad hoc) that keeps things exciting even after sinking a dozen or more hours into the game.

You might say that that's simply how any good shmup should be designed, to which my response is: well, Like Dreamer is a very good shmup. It really nails all of the elements I like about the genre, offering oodles of content and alternate modes to boot. The staggered progression of modes and difficulties will force the player to get familiar with all of the stages and bosses in a variety of contexts, so it manages to be accessible to all skill levels as well.

It's only 14 bucks on Steam. Check it out if you like shmups, or even think you might like shmups.
