Very simple but satisfying mechanic. Would appreciate a little more easing into the level before it becomes really hard, but is still a decent game. Good job!
ps. the reset wasn't working for me, had to use main menu to restart each time.
I'll think about something regarding the difficulty.
I think the reset bug came with the game export in html5 or something like that so I didn't notice it in development, sorry for the inconvenience, I'll fix it as soon as I'm back from the holidays.
