0.2.3 Game Over fix & 2 new modes!

There was a bug that you couldn't go game over in the coop mode. I fixed it

2 new upcoming modes:
I'm not going to tell you what both of the modes are because that will ruin some excitement, but I can say that one of the modes is a mode that you can play with an AI!

I'm almost done with coding the AI and then I'm going to work on the other mode, I'm not going to upload the AI mode before I get the other one done because I want to put them both in one update.
