Found a couple issues. If you are holding down the spin button when you respawn you can keep spinning forever and stay invincible. Also, if you go to the right of the levels, you can clearly see were the background ends. 
You did a good job making this though! All of my fails have felt like my fault and not the games. That is exactly what you want. And congrats on your first game jam! You should celebrate submitting a game!
Also, this is my game: Project Helix only play it if you have nothing else to do! I wouldn't want it taking away from the precious time you have left for submissions lol.

Hey, just tested your game. I'm very impressed by the way it looks and plays, especially considering that it was made in one week only. However, I kinda suck at puzzle games so I couldnt make it past level 4. The game is super polished and well made, and i love the way some parts of the text just have a little extra flair to it. (movement, colors, etc...) I didn't quite understand the objective though... :( Nonetheless, I think you should expand on the concept and release it here on itch or on steam eventually. This game will definitely rank very high. Thanks for your review and good luck! :)
