Thanks so much for the feedback Anders!
Like I said on the other comment, I'll definitely put in a Level Selector, and the eraser logic will be change. I originally design the game to be able to run on PC and on mobile, but I might just focus on a PC version first now and see how far I can bring it, this will be easier than making sure I support 2 control scheme.
I'm really glad you enjoyed the game, the praise I'm receiving for it so far is way more than I was hoping for!
