Thanks so much for the thorough review!! You're probably right about the shaders; it was our first 3D game, so we still need to figure out what works and what doesn't in the browser. The reason the game flickers like that when you reload is because we tried to optimize by only rendering the rooms that the player is in and the ones the player is next to, but didn't get a chance to fix that for reload, so when you restart, you are technically too far away for that room to render properly; it was a good lesson. Thanks for checking it out!
