Kabuto: That was the reason I installed it through steam and not via drm-free installer. It's funny I redemmed the camp tickets for the fun of it it thinking I'd never buy the steam version. The humble bundle nicely solved the issue by oferring both versions in a single purchase.
SirPrimalform: Actually, if you buy it from his site you get a (mostly) DRM-free version and a key you can register on Steam. That's the only reason I had a Steam copy before this bundle. I just wish I could use the damn DLC without having to start up Steam. =(
Honestly not a big loss. I just clicked on it to check it out and there's only seven levels. The first two are a joke on top of that so there's not much there. It adds teleport bonders since there's now a barrier between input and output.
