This is a cool proof-of-concept. I noticed that each hour has a different frog sprite and I liked that little detail, but the art is otherwise pretty barebones. It took me a while to figure out how to deal with the C-like patterns but when I did, I thought it was a cool use of the multiplier mechanic. About that second image- I didn't see that pattern in the game, and was a bit disappointed. For me, it cycled through spiral --> C --> spiral --> C before I stopped playing. It would've introduced an actual use for the x2 multiplier.
