I was a little confused at first on understanding what the upgrades were, I hadn't realised the shovel could be upgraded for a little too long, however once I realised this I made quite a good bit of progress. Unfortunately, I had hit a potentially game breaking bug whilst trying to return from one trip at one point, so I'll have to try it again later on and give it a full try, however the atmosphere was very nice and I loved the datamoshing effect (I think that's what it was intended to be, though regardless a very nice effect)
