Excellent game! I really like how it had a full slot-based inventory, lots of stuff to buy, secrets to discover, and some serious "skill issue" flying around. Currently I'm parked in front of a dreadnought with a drone inside that I cannot kill since my hand does no damage to it and my gun runs out of energy before it dies - time to grind for more stuff to get a better weapon I guess.
I like so much about this game I want to put a lot more time into it, currently I'm at 33 minutes and I want more! So that's a very good sign for jam games for sure.
I blew up mines and took the resource they dropped but I don't know what that resource was - maybe seeing a "you got +4 iron" or something would be nice. Oh, I really like the use of 2 places after the decimal for everything - it really made it feel the sci-fi environment. I would have like more variation in wall tiles, or at least horizontally flipping every other one. I walked into a secret 1x1 room where I was surrounded by walls and as I turned around nothing seemed to be happening so I thought the game was frozen briefly.
Great entry Dan, really well done.
