Hey, I just got around to playing the game again and WOW it's improved considerably. the endless mode/prestige was quite fun, the heat resistance upgrade is very useful (especially once you start re-digging the earth), and the museum collectable was a very nice touch, adding extra replayability to the game.
Though if you don't mind another small rant, it's a bit tough completing the museum. Maybe I'm unlucky today but I had collected like 15 key to the earth, 5 the lost hour, and 3 a perfectly normal rock before I found 1 tiny crashed UFO.
thankfully I did found it (it was the last item I need for 100% completion), but man it was really tough since with the bonus speed & the fact that these thing aren't affected by magnet just like the fuel, it's very easy to just... skip over them by accident. considering how rage inducing this could be (depending on how lucky the player is), maybe some kind of pity system would help, such as giving items that haven't been collected yet has an increased chance of spawning/being chosen over ones already collected.
other than that, everything is a huge plus in my book, love the update very much! :D
