Thanks for playing, and thanks a lot for the feedback! Let me know how far you get and whether you're stuck. Originally it's a 2-player coop game, so some of the later levels can be quite hard in single player mode...
Yeah that's what I thought, I was playing singleplayer and It was just two hard! Gotta find some to play with me!
That would be great, especially if they then also tell a friend... ;-)
However, you can also set the difficulty to "easy" in the options menu.
