It was a bit of both, I had to go back to the main menu the first time to find out TAB was for swap. Really great job overall, has some Lost Vikings feel to it! :D
Thank you!, also, tab basically applies a player++ thing cycling trough every player at the beggining of the level, however, I did not develop a way to keep doing that everytime a character dies. thats why you have to press tab a 3 times even if you only have 2 characters. But hey, it worked XD
