I give up. How do you crush the cars in Science Fiction level 4? I've tried hitting them from different angles, beeping the horn while I ram them, and landing on them with different parts of the car and there's not even a scratch. What am I missing?
There's a bug in the final bonus level (level 11). The initial performance bonus is "NaN", as is the starting time. "NaN" probably means "Not a Number", meaning that you're trying to eval a String instead of an int or a float. In effect, the van never reads as leaving the starting line so the level can't be completed.
Content Delivery is absurdly hard, but it's doable. The final trick is to make the second puke-assisted jump to the right chamber from the second platform instead of the first so you have enough suds to climb to the portal. That may be the strangest sentence I've ever written.
Level 22 is purely a twitch game. Unfortunately, it's virtually impossible with a trackpad because you can't navigate to the correct screen fast enough. Without a mouse don't even bother.
I dispute the idea that these are real words. Even if "tatu", "orff", or "echt" are actual English words they're so obscure that the game becomes a matter of luck, not skill. The graphics are good, so just change the pool of words and you've got something.
