Single player, by 
Inbetween.
“Crystall Instel” (I think it’s German) is a interesting single player level. It has no background eyecandy, there’s some tile repetition, repetition, repetition, repetition, and the caves are used wrong, so I’d say this author paid more attention to gameplay.
I don’t know how you’ll feel, but .I. had fun. Granted, if the tree branches had one ways, I’d have had more, but still. There are some interesting parts, and some nicish uses of sucker tubes (I want to be able to read the german text signs.. for some reason some are in german, and some english), etc. There’s also a place with lots of villains who you can total by dropping a turtle she.ll into.
Overall, while “Crystall Instel” is nothing special, if you want to spend a few minutes doing something, you might want to try this.
