A couple of small things I've noticed - when failing the mission return doesn't work and you are left with the amount of resources from previous deployment. Also, the web version seems to be too heavy on my browser, even the desktop build seems to be heavy on my laptop, but that is probably just my laptop is old lol :D
Really liked the UI and how you can see the map from above before deployment so it is easier to plan where to mine resources beforehand which helps. Not sure if it is intended just to see or you can move the area of the deployment but I was not able to change it.
I think when you just deploy the mission it is a bit too bright (maybe just me)
The day cycle feels too long. and feels a bit idle because there is not much to do rather than wait. I really like the idea of going back to the ship while wating, would be really cool to have something to do on the ship while waiting. Though seeing the planet rotation feels a bit confusing because I would expect with that speed to see day over faster :)
I was not able to wait over the day and was defeated :D I saw one enemy unit stuck and thought to mine some resources but it appeared that there were many more stuck over the time and they destroyed my defence in a moment :D :D :D
I like these new concepts you added, its really cool I think to have a map and a switch mechanics to the ship. It feels like a right direction to move!
