Too many little problems.

Controls are clunky and you have to resurface way too often. Its a mining game. Not a jet pack game. Down. Not up. Also bin fills up way to fast to ever let you really get into enjoying exploring at starting levels and major flaw is that when bin is full any blocks mined are deleted. The ore isnt either left behind to be picked up later nor is it picked up so that ore is lost forever in the game. Bin needs to be made bigger at the start to help you get into mining, not crafting. I played for an hour and resurfaced 10x times. Terraria is fun because you can just dig dig dig then when you go up to the top you have a boat load of stuff to sort and craft - its all your treasure. This game gives you too little of both. No mining. No loot. No treasure.
