That was NICE! A really clever way to fit inside the theme with a great execution. Even if the endless mode doesn't work, it doesn't matter. It's still GOLD!
At first you really feel lost when you actually try to figure out which monster you should pick up by remembering your orders and looking at the wall to get indications, but once you get the hang of it, it's a lot of fun! :D
Nice work guys! :)
