Ruff 'n' Tumble: unexpected game over??? WTF???

[mr_a500]

I don't think it's a bug. I think the developers felt that if you use a cheat to start at another "world", you don't deserve to continue to the next.

Get around this by starting at the beginning and pressing "Help" at the beginning of each level to get to where you want. It's a pain in the ass, but you'll be able to continue playing to other worlds.

Yes, that last level is a pain in the ass - even with infinite lives.

Lots of games have reasonable building difficulty until the last level, then it becomes totally impossible. (Dune II comes to mind)
