Found a bad glitch
Found a really bad glitch in the SE Generator room. I accidentally clicked the charge button a second time while it was making the first charge and the generator kinda freezes in that state of creating the charge. I tried it twice to make sure and it seems to do it every time. The game kinda locks up and never creates the charge needed for the power core.
Aside from that though, this whole series is increadibly awesome. 5/5 and 10/10 from me on this and the other three core games.
