Glad to see you finish your project on time, well done. Fully aware that you are a beginner and still learning, so don't take my feedback personally.

Music is too repetitive, you'd be better off making a slow compositing to drag the notes on over a 60-120 seconds instead. Making a more sci-fi eary feeling soundtrack with some random beats or taps to add tension. 

Movement feels very floaty, tightening up the character's motion will help (Increase gravity, jump speed and overall movement, add more friction or learn about Input.GetAxis, so we stop as soon as we release the keys). Getting stuck on the walls, is a little frustrating, and there is no kill zone under the scene to kill the player if they fall out of bounds. Would like to see WASD added and a double jump perhaps?

The combat is rough, but functional. It seems almost impossible to kill them without pressing attack, then instantly blocking. Noticed the 2nd scene's dummy enemy, has his attack bar go up slowly. Yet the other levels they spasm out, allowing the enemy to attack 2-4 times faster?

It's good to see the tutorial was built into the level itself, rather than having to read a massive wall of text or instructions. Scenes load fine, your combat/detection systems seem to work as intended(does need refining, as to be expected with a game jam). But overall worth a quick playthrough. Good job.
