I found a bug! I ran up to the 2nd block after hitting it with the epic weapon, and I teleported up hundreds of feet to a platform with a bat above it.
Levels 12, 14, 17 and 20 have alternate solutions the game doesn't accept.
Level 18 will only pass you if the solution is different from the example by one shape.
If not for the hints, this game would be impossible.
...you mean I have to do that ENTIRE thing over again? Seriously needs checkpoints, and what's with the Germans flying miles out of the "mission area"?
