Old: Ah, I remember playing an old version of this. It was fun, but looking at the screens, it seems that a load of stuff has changed. DL'ing right now. I suppose I'll edit my thoughts some time later.
EDIT: Wow. That last level... Trippy.
Anyway, I only completed it on Beginner so far, but I'd say Genetos has gotten quite confusing.
I still need to figure stuff out, like these supposed sub-weapons, IR Codes, the plot, etc.
