Really enjoyed it! Have a little feedback, to help you bugfix if you continue the project.
Major:
-Undercity and Apothecary "Scavenge" percentage doesn't seem to increase
-"Scrap" item never unlocked for me, and it wasn't clear how to collect it - most actions involving Scrap seemed to work, but I couldn't build the "Stall".
? -After force-unlocking some missing skills by editing the Save file (the three from the Stall), the buttons at the bottom left (Play/Stop, Repeat Last, etc.) disappeared. Maybe the UI expanded too much and they were pushed off-screen? Expanding the window didn't seem to help.
Minor:
-It wasn't clear how to progress at the "Nest". This and the "Stall" were the main two places I got stuck.
-Playing "Strip Poker" enough times causes it to move into negative numbers for "Remaining". This may be related to "Repeat Last"?
-General cleanup of the Tooltips and better explanation of the stats system would help the game a lot, I think.
Misc.:
-I personally had a little trouble with moving the map - I'm using a laptop trackpad, which doesn't make a R-Click+Drag action easy. Would you consider changing this to a L-Click+Drag?
