under the Grow menu theres an option for "start game"
Yes, found it. I believe the game becomes a bit better (or at least, less roguelike) in V3, because right now enemies better than me are spawning on me so I immediately lose every battle.
Also, what do the green orbs do? I haven't figured those out.
The orbs grow you a lot, same with the obelisks
The blue orbs I noticed (what obelisk), but the other spheres that are placed everywhere are the ones I am unsure of.
oh the smaller ones are just little things to absorb and add to size. Green just means its something you are big enough to break
