Congrats on finishing your game! It looks like there's a lot of content here, well done.
This is a neat take on the theme, turning the platforming into a sort of race/timed even and adding a nice bit of pressure. However, I think the game overall is a little bit unforgiving. As other comments have mentioned, wall-jumping isn't quite intuitive. It's in a good place for a game jam, but it probably needed a bit more time for refinement. The biggest hurdle here is visibility. The camera could be a bit more zoomed out to give players a better chance to plan and react. And the spikes should really stand out more. Anything that results in an instant loss for the player should be easily readable at a glance. Making them yellow like your water/acid pits would be perfect. And likewise - making your jump-pads a different color than the yellow that you've already taught your players is bad might help.
Still, this is a great little game for a jam. Very impressive, especially considering you're so young! If you keep making games and keep practicing, you're going to learn a ton and make some really cool games. Keep making games!
