Thanks for playing and glad you liked it! Sorry about the fire roundabout, its so easy to not see that hallway :(. For the water area, there is one ranged guy behind a detail that looks like it should block ranged combat, and he's definitely a bit annoying (apparently in a significantly not-fun-way). In the post-jam update I'll probably fix that. Yeah, showing intents at a distance would make sense, I also wanted that but didn't get to it because I don't have any way of drawing text in 3D in my engine yet, and ran out of time before hacking something together for that :D.
Because I have you enter full-screen by pressing F11, Escape doesn't exit full-screen (and, instead, let's it do game actions like open/close menus/etc, as I find it super frustrating when I press Esc and the game just exits full-screen under normal gameplay...), so you need to press F11 again to exit full-screen. That being said, I could probably throw a button on the title screen "exit full screen" (or just call it "exit") that drops out of fullscreen to prevent such confusion. I've definitely done similar things and not realized I closed an entire browser window until much later when I'm like "why do I only have 2 of my normal 3 sets of tabs open somewhere..." ^_^. Anyway, glad to know you forgot it was a web version by the time you were done playing ;).
