I'm gonna be blunt with ya bud, the only thing that interests me about this game is that its free. Theres nothing really bad about it, and if Minecraft and Terraria had a disabled baby this would be it, but I don't really see a reason to play this instead of either of those.
Anyway, criticism aside, my advice to you would be make this stick out. Don't associate this with Minecraft or Terraria in any way, advertise it as a standalone game. Trust me, when I see a game trying to ride on the rails of Minecrafts success, I immediately get doubtful of it, and I'm probably not the only one.
Good luck with this.
