Great concept! Definitely felt the “the factory must grow” urge. I wish bombs were more effective. It felt like I was bottlenecked on digging out resources at times.
There is a bug that you can place cannon drills on resources without an outside edge and it pretty much just deletes your drill since it uses the drill but doesn’t place it. I ran into that right at the beginning because I wasn’t sure what the rules were and my nearest resource was inside an asteroid.
I also found the drill stacking exploit, which trivializes the game but I assume was not intended.
Would love to see a complete version with more mechanics!
