Jump×3

Kinda boring, very repetitive. I went through 14 rounds doing the exact same thing. If you're not forced to change tactics after 14 rounds, it's really not worth playing another 14. Throw in some obstacles other than the randomly changing pillars. Force the player to do something other than the biggest jump possible. Maybe force a landing here or there. Also, it's a good idea to actually tell people how to play the game within the game. I was told to click to begin, so I assumed clicking made you jump. I obviously died, at which point I was told to hit space to begin, so I tried jumping with space. then I learned that the platforms were not platforms, but some kind of death pillar I wasn't allowed to touch in any way. Point is, offer some explanation in the game, and provide better obstacles, and you'll have a much better game.

Boring.

The jumping is a bit inconsistent. You should code the game so you jump only when the spacebar is released and pressed again to avoid small sequential jumps that are ineffective
