Interesting
This game is really interesting. I don't ever recall anybody ever doing this before as a 4 player game. But I need to add some suggestions.
#1. Put unlockables.
#2. You need more places
#3. Campaign mode makes a game way better.
#4. More weapons (there where like 4 in the game. At least that is what I have seen.)
And I was taking it as what you said in the description that you will ad ai. And there is a bug. When you press up on whatever charecter you are controlling instead of jumping you float.
But this game is really good :)
I'm adding it to my favorites.
