What art lol, haha thank you, I'm glad it left such a positive taste despite looking all blocky, we left the control scheme for the keyboard on the game page but I guess its easily missable.
And yeah you're absolutely right we should've added a "congratulations u saved the world xd" popup at the end, we were using this demo in an expo so we were around to tell players they were done.
There's going to be more combos and weapons in the future so stay tuned for that, again, thanks for checking it out!
