I appreciate the work you put into this and the concept is really nice but I think it has a long way to go before it becomes something special. I imagine you're a new Unity developer and if that's the case then I want to praise you for making a complete game and uploading it to the jam! That's what these jams are for and they are great for learning and improving skills. I'm glad I played the game and I hope you'll give my game a try too! Here's a few things I think could help you:

The character often gets stuck on walls and sometimes even the floor which makes movement janky and difficult. The way to fix this is to create something called a physics material which has a property for friction. You'll want to set it to 0  then apply the physics material to the character to eliminate this issue.

It's typically good practice in games to make enemy and spike hitboxes a little smaller than the actual size of the object. This makes the game feel more fair which results in a better experience.

Well done! You did a great job for such a short amount of time. Take some time to work on the movement or maybe add some rockets so that you're flying instead of jumping? I really liked the background music.

I like the way the game looks, and the  gameplay is fun! However, the UI is a bit simplistic with some spelling mistakes. Also, the jumping feels unrealistic as you can change momentum in the air, pause in mid air to drop. I got stuck on some corners too.
