Right; played the demo, here's my two cents:
Overall I like it. Nice setting, good writing, nice character art; just a neat idea altogether.
The 3D...ish aspect I don't get; all it seems to add is endless drawing order glitches (if this were OTTD I'd say the bounding boxes aren't set properly). That plus that the maps are pretty dull (a bit of an empty corridor syndrome going on; tighter locations with more interesting things going on would imo be preferable), making for a worse look overall than it'd have to be. I'd also say that interaction spots are sometimes a bit finicky and not exactly obvious always; something that could improve how smooth the game is to play maybe.
The "perk" screen seems to have a bit of a weird order and I wouldn't have minded some reminder of what the stats do during level up - but these are tiny things. Only bug I noticed was the computer as mentioned above. "Whatever".
For the demo it didn't matter and I didn't explore it in any depth but I'm a bit "worried" for the management aspect for the full game. It seemed to me - but I didn't try, so maybe I'm wrong - that all upgrades just increase your income and there's really no downside to just spend all your money, sleep, upgrade, make more money, sleep, upgrade, making even more money ...
It might be that a counter-effect of sorts is needed; ie. if you got a fancy dining room but only poor patrons it costs money instead of making money (and, ok, I get it's your salary, not the club income, but giving that I'm using it to upgrade the club, well ...).
Battles are fun; didn't have any issues with those.
That is all. Good work; I'll keep following development.
