Mega Miner hmmm
What with Minecraft being popular n such, as well as this game being a mixture of both Motherload and a game on Xbox live (something 'miner' related lol) I'd say that: although the concept isn't original, I still enjoyed playing the game while I wait for the Minecraft sever I usually play to be back online. So... not bad I guess... still though, you could of altered the concept a little bit. Maybe add some sort of rpg elements, or perhaps monsters to kill, maybe both! Anyways, if you intend of making a sequel, I suggest adding some original content.
