One of the best entries in my opinion. Very innovative take on breakouts. I like how stuff explode and how enemies attack you. The game is very well balanced as well! My sole issue, bit more personal, would be the theme. Kinda would have liked to see more than just "eyes" and "squares". I like the powerups too!
Also, i would have liked the mouse cursor not to be ther. It kinda was distracting to have the cursor visible. (though I get it's important to avoid making the cursor go out of boundaries, but if you lock it and make it unluck when yu pause it should be fine)
Also, nice to see you did that with game maker studio :)
My best is 35!
