Slime-san is a retro styled platformer that plays like Super Meat Boy. The controls are tight and the gameplay is incredibly quick. You will die a lot, but it's painless and you can get back into the game in mere seconds. It's got loads of leaderboards and speedrun trophies if your into that. The game is really charming, my first time visiting Slumptown had me smiling, Japanese cyberpunk meets pixel art. Completely uneccessary, but makes the game so much better.

I found the default keyboard controls a weakness for the game, the dash button is mapped to E, which is right next to your WASD keys, but many obstacles have you jumping, changing directions, and then dashing, I wound up remapping the dash to M which fixed a lot of problems, although gamepad is recommended.
