This is really neat! I like the synergies between some of the vehicles - that you can follow a miner with a hauler, or a digger with pretty much anything else. It would be neat to play with a bigger group: it seems hard to justify running around as a scout with two people, but could be really handy to avoid a bigger group all wandering in search of resources.
I feel as though the biggest thing I’d like to see is more of an obstacle to harvesting the resources - maybe enemies running around or something - but that’s a big ask for a jam game. The only other thing would be a little “beep-boop” when chat messages come in (but having in-game chat in the first place is hugely impressive!).
