Fun, interesting take on Asteroids. Interesting that the enemies have screen wrapping but you're confined to a box, which makes it a little more challenging. I liked the powerups - I think that the 1000 powerup is overkill given that the 100 one can be used 10 times, but in later difficulties it may become necessary.

Yeah, I didn't really implement them the best way I could. At some points you can just use the 100 points powerup forever because you get points by destroying the pebbles with it, so you can get all the points you used and then some more with it (specially later on when there's a ton of enemies on screen). It was my first time adding powerups in general so I'm happy with this for now, but I'll look more about balancing and functionality on future games. Thank you for the review!
