This must be the only Rust game in this jam. Impressive in itself. I did have a hard time playing it but got a bit into the game and could attack some enemies and ascend and descend stairs. You did have instructions on your git page which is great, but I think they should be on the itch page directly to make sure players see them. Its a bit of a hunt to get them now. The looking up and down made me disoriented, as well as the movement. Seems like it is a 2D game in the sense you can only turn around 180°. Would be nice with some sound as well.
Keep at it! Experimental guy ;)
