The size and scream were from part 2 of the jam for reality changing. I had random speed changes in there too, but I found they were more irritating then fun so I removed them from the possible effect list. I had increased fire rate as well, but as you found, hitting space triggers it even if not near terminals, so my test player would just spam the space to they got it. Time prevented me from hooking up the reality distortions properly to the player units. Not sure if I'd keep them in I'd I were to expand upon it.
