This is absolutely the best "you jump on a timer" game I've played.
The glide mechanic, the clock pickups needing to be activated strategically, and the varying (but clearly indicated by the UI+sound) make for a wonderfully deep game. This feels like a game built around its constraint in a way that can be difficult to do. Congrats on some really nicely designed levels.
Super polished stuff, none of the critiques I normally have apply to our game, it's just good clean fun. I'm amazed you pulled it off in 48 hours.
