Thanks for playing!
I think the browser mode just takes an outrageously long time to load. This was my first time building to WebGL and I thought the long load times at first were just a fluke (took a solid 5 minutes). Now when I run it, it loads pretty much instantly, so I guess it's cached or something like that. In the future, I'm going to have to learn how to optimize load times for WebGL. To your other point, yeah, if I could re-do this game I would put the doors at an angle so they were more visible.
At any rate, glad you liked the game!
