I like the concept of having to buy moves instead of a whole ability. Also the jumping and sprinting while rushing through the level felt fairly good.
The environment was basic but it created an interesting atmosphere.
I feel the timer was too generous and didn't build any pressure. Also sfx/music would have greatly contributed to the feel of the game. But I am sure both were due to time constraints.
Either way, congrats on your first game jam submission!
Also quick tip if you want to avoid the two awkward overlapping fullscreen buttons next time:
Make the viewport dimensions setting on itch slightly taller than the game (e.g. 1280 x 720px -> 1280 x 770px) and disable the itch Fullscreen button.
Then you have the one fullscreen button from unity you can click and actually works.
