You can play it here.
I wanted to try my hand at a similar game, but my design goals are a bit different:
Runs in the browser, so everyone can play
Supports up to 8 players, if your browser can deal with 8 gamepads. (For now it's single player only tho, keyboard and mouse)
It's easy to learn and hard to master. Newbies welcome. =)
I'm coding it entirely in Elm, I want to see how I deal with interactions in a flat entity hierarchy with a purely functional language.
