Thank you so much for the kind words and detailed response! I definitely agree that having a better indication of limited vs unlimited actions would be useful, though I'm unsure how I'd do that without making the action buttons larger to fit a done/max counter... An icon or different colour would work, but people still have to learn what it means in the first place. I'll throw a note on the list to think about for if/when I work on a content update.
I had intended to make tooltips for the skills, which would've broken down your current multipliers, but ran out of time (for my self-imposed deadline). I may be able to fit them into the bugfix patch I'll do in the next few days. That combined with the post-loop breakdown screen should clear things up.
Added note to tweak the 'Force Ground Floor Door' action in the bugfix. It was only actually hidden initially due to a technical limitation which I then fixed for the Admin Door.
I have a few plans for the Action and Inventory panels, but they'll all likely have to wait for the content update. Currently items are consumed in order of how much they restore, which honestly is just a holdover from Increlution, but Terraformental has increasingly become a slightly different style of game, so you may be right that it should change... Yeah, I'll try to fit this into the bugfix.
It can be difficult to decide how much to fit into a single log message, as I didn't want to have a single message scrolling off the screen, or generally put people off reading them. But you do raise a good point that I could add extra 'Explore more carefully' actions once you have access to all the unlimited resources and are stabilised.
As you say, harvesting when full would be very exploitable for farming XP. The closest I'd consider is if your inventory is full, but you're missing enough of the resource that you could instantly consume it, then maaaaybe? But I'd want to build up more of the game, so I have a better idea of what impact that might have on balance before I made that kind of change.
I can definitely add a 'disable other actions' warning of some kind on some actions, but it'd likely be in the content update.
Thanks for the offer - I'll be sure to keep you in mind if I get around to doing beta tests. Though if I'm honest, I doubt I'll get it to the front page (as nice as that would be) xD
