the 2p is won't work!
the vs player is totally useless for now...
how can i play with 2p? is there some setting for it?
I assume you mean the local multiplayer; only one player can play with keyboard unfortunately. The other player will need a controller.
If you mean online play, the itch.io version only has direct connection via IP addresses and ports. The Steam version has the normal Steam online play stuff
It's been a while since I updated this version though, you might want to be on the Steam one! A free Steam key came with your purchase.
