This was hilarious (and frustrating but that seems to be the point.) I love the filthy hand artwork as well. Getting the right keys when the game speeds up is insanely satisfying. Really fun, cute little game, and a good take on the theme!
Side note: Could you potentially drop a link on how you got unity browser games to work on mobile? I haven't seen to many games so far with that capability. I had looked into it a bit but everything I tried wasn't working that well. Not sure if my google skills are failing me or what. No worries if you don't feel like digging it up. Awesome work!
