I really liked this game. Probably the most purely fun game I've played on this jam so far. It isn't necessarily the most innovative, but goes to show that doing something elegantly and well means more than doing something ambitious poorly. So congrats on that.
Also, your UI and user friendliness is sooooo much better than anything I've seen thus far. That was such a big strength.
Though simple, the gameplay was engaging and fun. My one complaint was that there was no in-game UI for my current height or high score (unless I missed something obvious), so I couldn't see how I compared. I think it would help replay to add a little tension for the player to know when they are close/how close they are to improving on their last run.
And maybe a nitpick. There were some instances where the blue booster pads were almost on top of the pink ones, but I was blocked from accessing them. Consider adding some code to prevent an overlap of pads.
Overall, excellent game and great design on all fronts. I really enjoyed it.
