This game had serious Celeste vibes, with the hair and the precision jumping, haha!
I like how you start the game with the wall jumping, to teach the player what the character is capable of without much hand-holding. I also like the idea of a countdown timer for these levels, as it brings a great sense of urgency and challenge.
The first level did feel a bit punishing on the timing for me - on my many attempts, I kept missing the door by a few milliseconds. The player's controls also felt a bit sensitive / slippery, so I frequently ran into spikes. Granted, I am terrible at precision platforming games, so you can take this with a grain of salt. Overall, nice work!
