Neat concept! Getting things going was a little rough around the edges, but the tutorial is definitely a nice touch and helped keep it playable. I also really liked some of the art/animations.
I lost on Carbon and couldn’t figure out what was wrong, I had it bouncing above and below 10 but it never seemed to trigger anything else until I lost. From the project page it looks like there are more requirements that just weren’t clear to me at the time. I think making whatever conditions weren’t currently being met clear somewhere would have helped a lot.
Overall, though, nice job!
