The idea is really cool and has some potential, but it felt unbalanced and frustrating at some points. Still, game actually looks really good and is a good experience. Really well done for only 1 week of work! Good job!
The difficulty spikes, especially from level 2 to 3, felt really steep in my opinion. Might as well be just my opinion of course :). I'd also add a restart button, by the way, not just an X to go to the menu.
