Short and sweet, a very delightful platformer that doesn't overstay its welcome (if you don't go out of your way to try and find all those damn EXP cubes.)
I'm especially a huge fan of its overall grunge... AND GOD, DOES USING THAT DRILL SLAM FEEL GOOD -

(also, i actually adore that hand-drawn artstyle used in promotional material, its KINO)
