One Man´s Trash

This is the sort of game that I love to play. I have gone through bunches like it and given positive reviews, but I can't here. The main problem is a persistent bug that continued to plague me all throughout the game. I have posted on the forums, and searched all over the internet, but there do not seem to be any solutions. In a game where you are digging a hole, what would be the worst thing that can happen? Your hole gets filled in and you lose all your progress. That keeps happening to me as I play this game. Dig, save, close. Start it up, and everything is filled back in with no resources that provide money, just dirt. This is why my play time is so high. Not out of a sense of: 'oh I had a lot of fun, and there is just so much content to this game!' No, I had to keep digging my tunnels back out. As you dig in this game you uncover trash, and then ore, that will net you money. With money you buy upgrades. However, when you buy upgrades nothing really feels good to improve. Everything just says 'Capacity: +5%' or 'Strength: +5%'. Everything but the inventory size (and that is only increased by 1 each time) is increased by 5%, but what does that mean? I feel nothing buying these upgrades, no sense of progression, no drive for more. Add on top of that, that to keep buying upgrades and sending the rope further down the hole, you need to buy milestone upgrades. It is just money spent on nothing but the ability to buy upgrades. Feels like the opposite of fun to me. It doesn't make me want to keep upgrading and moving forward and playing, in fact when I reached these it often made me consider stopping. In these sorts of games I dig for achievements, pun intended. Unfortunately, for some reason, I cannot seem to be able to find one last specialty item, despite getting to the bottom of the map and beating the game. I have dug all over, through all the extra side tunnels, mines, misc locations, and used tons of scanning devices, with no luck. Despite my tunnels getting filled in, I have dug to every item in this game using the scanner, and I can't find the last one, and I am not the only one posting about this issue. On top of that, if you pick the mystery box reward at the end, rather than selling the data drive, it is impossible for you to get the achievement for a million dollars and will have to start over. You come nowhere close to earning a million through mining; and I am not starting over. I think the issue is that the data drive counts as the last item, locking me from getting the 1 million achievement, the achievement for the specialty items, and from there the achievement for finding everything. Extremely annoying on top of an annoying game system, and a horribly annoying bug. I would advise that people stay far, far away from this game, even on sale. It is buggy, annoying, boring, and not particularly fun.
