This game is amazing (save for a couple weapons, hehe). I would love to see an update (hell, just sell it as a sequel and I'll buy it) with an additional carrot beyond upgrading your droid. If there were a final depth level to try and get to (maybe there is?) or something that felt more like an end other than upgrade everything (which I'm already enjoying doing), I would love that. Maybe a sequel where you have to rescue other droids and have to drill back up to the surface to get them to the rescue ship?
