Final level is really easy, just zigzag the one player left/right. I suppose it isn't necessarily meant to be hard always, but it started out pretty hard and got easier.
Thanks for playing, and I’m glad to hear to you made it to the end! I wasn’t sure if levels 5/6/7 were too hard or not. I’d like to include some proper challenges for the two player levels, I think a future release will explore that more. Agreed re: the final level, it was meant to be more of a victory lap than a challenge - i think it would pay off more with more challenging two player levels building up to it.
