Hello !
First of, I love this game : the sfx is great, feels chaotic at times when multiple cpus opponents but I like it. The graphic is simple thus effective. I did read about changing the background - last discussion of this page - with two png in the data folder but I've looked inside the assets with bundle extractor and there was multiple texture2D so if you could point me into the right direction I'd love that :)
Also for joining when using a keyboard I couldn't figure that out : I setup the keyboard configuration for player one as I like, then player two. I choose 2 players, and then it is always the cpu, I don't know how to make it local multiplayer.
Thanks again for your time and your game :)
