It's a bit lazy to have the map but to be unable to use it. I get you're using a sort of template at this point but it would be helpful if I could just go from butler's room to e.g. in front of the bathroom or from top of the stairs to reception.
Pretty great series so far, plot twist with Marco was quite genius. Didn't think I'll be plaing "modern" pixel adventure games anymore, made me want to release my own at one point too! Wrote things in Unity before and Construct looks even easier. PS. Looks like you forgot to style the "I SELL GUNZ" on the sign of the shop.
Go into swarm mode, pay 20.000 for a weapon. Is worst in every way than a default one. Are you serious or screwing with us? UI is terrible as well, at the beginnig I couldn't even figure out what to click to buy. Not to mention that buying supplies is a pain. There's just so many small things wrong with this game.
