I can't kill bad guys with sword and doors diamonds don't work. I also didn't understand how to win or die. But the design and music is very nice.

Thanks for trying it out. So I've got a lot of work to do on making things a little more clear. The first two npcs you meet are friendly, you can interact and speak to them. I do plan on making it possible to aggro and kill them, but it's not there yet. Past the second one you can press the right shift key which will warp you to the alternate dimension where the door is gone and there's an enemy you can attack and kill. I'll make some improvements this week, and give people some more things to kill.
