I'm a fan of geometry dash, so I like this game! It's not as hard as Emara made it look during the demo ;)
Though I will say I got to the final platform several times before understanding that the blue cube was the win condition, which was a little frustrating. As mentioned during the meeting, I think that some of the timing windows were a bit tight, especially with the jump. I recommend changing the jump from a parabolic arc to a sharper Up-Down motion, if that makes any sense, so you're less likely to get caught on the lip of the pink blocks.
And of course, the music is great.
