My god, this had me hooked completely. The upgrades are crazy good, I didn't quite get all of them, but holy crap, do you ever get powerful. I enjoyed the game a ton, so take this as a nitpick, but I did find the initial pacing kind of makes a lot of it feel a bit arbitrary. Getting the laser makes the mining so unimportant that it made the grinding I did to upgrade it feel superfluous. Once you get the laser, the pacing gets back on track with pretty few bumps and considering it's a game jam and there's a surprising amount of content, it's really solid from then on. Extremely good entry, I played this for so much longer than I should have
