Hi. So, while working on GridSpace, I was getting a little discouraged because the FPS was dropping, and I was unable to maintain a consistent 60 FPS.
I found out that the main problem seemed to be that NPCs were their scripts running constantly - fixing it so that they only work when on-screen helped to fix it. I'll have to work on optimization, but the BGE is quite capable of pretty much any project a developer can throw at it.
Also, I've got a health bar up and running now. Moving over corruption will take your health away, also running into enemies or their attacks.
