I like the concept here, really cool to change the whole game at once sometimes, though next time you should produce your own art / source art that blends more nicely together for each "stage" :)
I could defiantly do with forming a team next time. I spent to much time trying to find the right assets to match together. Pro's and con's of being a solo dev :). But thanks for the feedback, and i'm glad you enjoyed it!
