This game is really simplistic, but it is very fun and hard; I had fun. I don't like to brag, but my high score is 103.

Good stuff, Great design style, Fun little time waster.

High Score: 19

This is pretty simple, but that seems ot be the point in the design. Despite being simple, you still added things that help make it not look like an excuse (cute pixel animation trail, platform generation is clean, increasing speed as the game goes on, etc.).
I would say that it'd be good to have something that tells you that yu have a double jump, some smooth/calm music (vaporwave or LoFi?), and maybe a leaderboard.

Otherwise, this is pretty good.

Fairly decent game. It's nice and simple to play to turn your brain off with. The only real problem I see with it is that after you reach a point after 20 points its almost impossible the double jump in time for the two bottom stacked blocks. Either way, it is still challenging and simple fun.

Nice simplicity. Would look better if the number text font was the same as the rest.
