Good to see you this DemoDay! I'm happy to hear you like the atmosphere of the game. It's still very rough around the edges, so my goal for next DD is to give more of a real vertical slice with more npcs and actual dialog. I'm shooting for the art I have now to be the bare minimum standard. The music is just CC stuff for now, hoping to have some friends make an OST soon.
For the controls, I'm thinking Input prompts are in order for the Pre-Round sections, as there's some features people are missing. For example, you're actually able to heal yourself between waves by selecting the main character and pressing N, then up or down. You can do this to repair the cover objects too. An actual tutorial is a must.
I'll be giving your latest build of Northwest Passage a go soon and will give feedback; very pumped to see you're still working on it. But first, I must take a nap.
