Such a creative and novel idea, and you used it in such a good way. I loved how intuitively every mechanic was introduced. I was never in doubt what I could do, even though no text was presented. So good! Without a doubt in my mind this game has the bones to become a full release. The added mechanic that some of the moves could be timed proves that there is more to explore than just "pick up a power and use it". But that in itself is enough for a full game I feel. And very good idea to focus them around movement, and not other stuff like combat. I do have some criticisms, but it is only because I think the game has so much potential.
First, the controls were a little too sharp. I think you could fit more intricate puzzles in if the movement was slower and the controls easier. Some of the puzzles were you had to pick up and use powers while in the air was very tricky.
Second, I would have liked the game to be less punishing. Dying and going back to start became frequent and a little tedious. Maybe when stepping in lava, you could lose some health and jump back on the platform as in old games like Ratchet and Clank.
Lastly, it felt like the game couldn't quite decide what it wanted to be, but then settled into a puzzle platformer. I didn't care much for the boss fight in the early levels, and I think if you make a larger game, you should focus 100% on being a puzzle platformer.
Anyways, that's my thoughts. This is the longest comment I've left this jam, and it's because I feel like this game has huge potential. In any case, keep up the good work!
