I'm playing it right now using a gamepad and the first thing I noticed is that the game registers button presses too sensitively. Sometimes when I just want to move left or right I fall though the platform I'm standing on because apparently the game also registers that I slightly press the down button. Other than that it's a fun game so far and the simple mechanics feel well executed and "natural". Also, the music is really cool! :D
I would love to see the finished version of this!
