Cool concept here, I liked the upgrade options after completing a level. I also liked the music choice, but it didn't loop after it played through once.
One of my favs I've seen so far, well done! One little thing I found was as I had gotten big - if I got caught by a dropping camera, the next one would also see me before I could move. Otherwise, I definitely enjoyed it.
I like it and the controls feel smooth. There were multiple times where only mines spawned on screen and there wasn't anything I could do to progress other than starting over.
