The idea of not controlling a standard input in a platformer is the first thing that came to mind to a lot of people, I think, but the execution is... well holy cow it's amazing. The way you expand on it with mechanics such as the constantly changing timer, the +time and -time pick-ups, and the platforms that toggle on and off are such great ideas. They would've been just good ideas if it wasn't for the awesome level design, that sometimes feel even a bit puzzly. Navigating the designer's creations was a joy, and constantly impressed me on how well they used the tools provided.
The movement and feel is on point, too. Not to mention the sound effects, music and art. Everything fits together in such a way that makes me question how you were able to make something this good in such a short period of time. Kudos to the team, for making one of the best games in the jam and just an excellent and well polished game overall.
