Looks like it's  has not so much functionality, but still playable

FIVE STARS! a lesser game would use more colors or shapes. Not this sweet 7 minute effort. Curse you, red square! Go back to the top of the screen where you belong. :)

The red blocks kinda jitter around when the spawn location changes, and it ends kinda abruptly, but thats fine.

Really nice work for 7 minutes - it's definitely functional which is all you can ask for.

Really nice! one thing though, the game crashes once you get hit which is a little annoying. 

This one isn't bad honestly. I'd say you made good use of the 7 minutes provided and transformed that into a fun little arcade game.
