You win! Thanks for playing!
The mechanic felt like a unique asset and I feel like you could've done so much more with it (which you might've initially planned to? Haha), nonetheless, I saw the potential and loved it! The controls were responsive and worked very well.
The audio got a bit tedious/repetitive, but that's not much of a biggie! As for level design, I really liked the ideas you put in there, challenging and interesting bits, but I do think the way the character controlled itself could've been a bit more lenient - for example the final jump (drop underneath the spikes than jump up to the next platform) was incredibly tight it felt like. Perhaps a slightly smaller hitbox for the player would do the job already!
Nonetheless, grats on submitting your first game jam ever, a playable game with a full gameloop! Congratulations!
