Nice demo! I really enjoyed the game loop once I settled into it. It gets the player in a nice flow state, and I definitely had *fun*.
My main criticism is clarity. It took me a little while to understand simple things like why my buildings were greyed out (no applicable materials) or that I needed to double click things.
I think some small changes could help with this, just to prompt the player a bit more.
I also think keywords would help, like highlighting all the gameplay terms or something. Would also like a way to tell high/medium/low quality materials at a glance.
Gameplay:
I thought it was fun, but quite easy. I mainly focused on selling stuff for trader quests, and I never really found myself resource constrained. My main issue was finding buildings to make higher quality resources.
I also think an up-gradable “hub” would help a lot, or maybe a big goal like your debt in animal crossing. Then you have incentive to stay on planets instead of just leaving once you hit quote.
Art/Music:
I know it’s all a WIP I really like the planet’s background art, and the trader icons. The buildings could be a bit more distinct, things like steelworks or atom smash kind of are just a blob of yellow or grey. All the music and sound effects were good, not problems there.
Bugs:
Module compactor description says 2 <blank> modules -> 1 High quality module. Think it’s missing the “medium module” string.
