Hey, your game wouldn't load for me. I can play other Unity Web Player games, but yours just gets stuck on the Unity logo loading for some reason. I did watch the video though. (UPDATE - probably not a problem with your game... looks like I'm having problems w/ all Unity web player games on itch, even though they seem to work on other sites)
Do you use some special plugins/systems to get your voxel art in Unity? Or is it really just standard 3D mesh files stylized to look like that?
