A really fun little idea, that got a lot harder than I expected when the green sphere gets introduced. Definitely a solid concept that could be expanded on further :)

Feedback (if you want to keep working on it, or maybe just things to consider for the next jam):

• The music track got real annoying real fast. This can be avoided by having a longer looping audio track, and make it persist through levels/restarts. Especially in a game like this where you are restarting so often, hearing the first 4 seconds of the track takes it's toll real fast.
• Add a little bit of juiciness to the deaths, an explosion or some little visual tell, that you died. 
• I know you were embracing the "Unity Default Project" look for this (no offense I hope haha), I've discovered a great trick to avoid that is to see the Clear Flags of your Main Camera to Solid Color, and choose a color. That blue/grey horizon is ingrained in most game jam players heads at this point I think haha.

Great work, you made a genuinely interesting game design in 48 hours, that's definitely worth exploring more, keep up the good work. :D

I didn't really know what was going on but moving the level instead of the player is a really interesting concept. Nice game for a first jam, keep at it!
