My game idea is that you are a brain, and you manage to get into some ooze in order to move around faster. If you take damage, the ooze flies off of you and eventually you have no more ooze, back to brain form. You can find the ooze gibs laying around and get back to ooze form though. Going to make a few more variations for what the brain can enter (vehicles). That’s my “shapeshifting” piece, I hope the voters approve 😉
