Really great first game - such an interesting concept! Love that you funnel players down a critical path which can slowly become trimmed away / overcome faster with the unlocking of abilities. The platforming itself also feels really solid and precise, so well done on that.
It's addictive, I managed to get sub 15s because I kept trying to get better and better :D pretty sure I could trim even more off with enough practice!
Only thing I would suggest adding at this stage is a "fast restart" button. Unless I missed it, one needs to get to the end to start a new timed run.
A nice to have would be a "ghost" of my best time so I can see how close / ahead I am.
Again though, great job on your first game! Can definitely see it being fleshed out with more levels that incorporate one-off/unique mechanics, enemies, biomes, etc.
