This is an incredibly ambitious idea presented very well, but missing a lot of the quality of life considerations that I feel are necessary to think about when making a puzzler in this manner. An explicit grid system, slower player movement, and a more gradual escalation of new mechanics without making those new mechanics instantly a part of the puzzle, all would have gone a long way to making the process of learning and interacting with the game a lot more seamless. Obviously a jam doesn't give you the freedom to implement all the quality of life features you'd want considering the very short time frame, and in that sense, you guys did a fantastic job bringing to life a proof of concept here for a future fully made puzzle platformer if you really wanted to explore this idea further!
