Love the wacky artstyle! At first I wasn't playing on fullscreen on the browser so I didn't notice the sword pickup and got lost lol, and then I also tried to drag and drop the bones to the highlighted...uh...how do I call them, green spikes? And it didn't work so I was confused, and then later I read that I'm supposed to only put them in the central alter, and then I got it. But it was too late because I right clicked on the 3 bones and they disappeared from my inventory, oops. I think if you made a clear visual distinction between the central alter and the rest, like a playing animation with an item slot on top, that would've been a more understandable visual cue. And then you could also limit the first time player spawns to not move the camera and not let the player wander off too far from the beginning just to force them to pickup the sword. Because otherwise you can't really start the game anyway. But other than that, the killing and the swording was satisfying, and it's fun to go around hitting bushes on the ground. Well done!
