Is it CO-OP? Would be cool if one person could control the veichle, and the other the water cannon. The game would probably need to be a bit more intense for that though...
It can be! As long as the other person is sitting next to you. You just control the player with the arrow keys, and the hose with A, D & spacebar, so you can easily divide those tasks. I usually do half of it when I show it to new people, so they have time to get used to it.
I would love it if we could have made this a full endless runner. Sadly, since we only had 2 weeks to work on it, we weren't able to make it auto generate chunks, so it's only a set length, and the level is the same every time.
