I hate it how you lose all your ore while you dig. It's not funny when you grind all the time, getting enough money just to buy an upgrade, to dig down, get enough stuff and then run out of the battery 5 blocks before the surface... Can't i leave my ores where i died so i can pick them up later? :/
I liked the game. Wish there could be way more weapon upgrades (those big one's, not the small one's) to experiment with the possible combinations. The amount of weapon changes for this game makes it addictive, guess a lot of people actually wanted to check out the combinations ;) Maybe after completing the Beginner / Hard mode we should be able to enter something like sandbox mode, where we could select which upgrades we want to apply to our weapons and see how it would look? That would be awesome.
