Neat concept for a game.
Game adheres to the Jam Theme very well. I looked forward to exploring the map.
It was a good idea to include a double jump rather than just a single larger jump. Gives you more control. Cool that you managed to make multiple paths to progress during the timeframe too.
For improvements, a mouse sensitivity slider is a must. Sensitivity was way too high for my mouse. Also, I'd suggest making higher parts of the level be directly above lower parts to create a kind of emergent checkpoint effect (quite common to games in the genre).
Overall, a nice submission!
