If you want some constructive criticism, I’d suggest treating the WASD keys and the arrow keys as different players (so two players can share a keyboard, without needing to buy a controller)
I didn't think of that at all when I was slapping this together, but that's a great idea.
and probably making the the player objects look slightly different (maybe different lance colours?)
The original plan was to have proper art assets to replace my temp blocks, but my friend got busy. I'm thinking that adding some sort of color effect should do the trick for an updated build. Like, player 1 has a red circle, player 2 gets blue, and so on.
