You're basing this comment on the original version? Because in the paid version, you can by no means just "not touch the keyboard".
I tried it out of curiosity while writing the review and the paid version has a lot more to it and is a lot better. Sly-lupin mentions the generation of the maps. Over the review period, I didn't run into the same map twice. I've run into *similar* maps, but nothing identical.
There are definitely some set patterns to stop them being unpassable, but by no means was it the same three or four areas copy-pasted in different orders. I'm not sure if you're basing this off of the free version on kongregate or not, but the paid game definitely has more than three or four areas. Especially when you account for apocalypse mode and user-created maps.
