He's a speedy dude with a cool hot and attitude! The game wants to connect to the internet for some reason. The starting audio volume made my ears bleed; the non functional options button mocking me. The ESC menu buttons cannot be pressed with the mouse. I don't think it says anywhere that LMB is attack.
Going fast feels good and can be controlled pretty well even with mouse and keyboard, so you're nailing that. You get really sluggish and useless when you slow though, but maybe that's the point. I hate falling into the water... Hope you'll make it less annoying to get back up in the actual game. I don't play enough platformers to give great insight into much but the jump could be better, feels like you hit the apex of it a bit too late or something, I dunno.
