hey, thank you for playing my game!
I added the second phase because I thought that the first phase alone wasn't enough to fit the theme. I missed too the "Undo" button, but creating two games in one took me so much time that in the end I didn't have the time to add it. In the future games I'll probably focus on one type of gameplay, this was an experiment :)
Oh, thank you for your tip, this is actually my first puzzle game! And about the title, I don't know, my friend (FUSED) made the logo and I don't remember its meaning...
