Not bad, one button clickers can be quite entertaining as they are very easy to approach but hard to master (if balanced well). I think the speed acceleration here is pretty well implemented because just when I was beginning to think "this game is too easy", I realized that it's actually speeding up quite a bit.
The only thing I failed to realize until later on in the game was the fact that everytime I hit an obstacle, my character falls closer to the evil eye dude. For a while I thought the game is yet lacking a death mechanic and that I can just hit stuff without a worry!
All in all, it's a fun jam minigame
