Weird, the look sensitivity is perfectly normal on every computer I've played it on. I'm sorry to hear it wasn't working. But yes, I wish I had would've had time to have more than a few textures, better lighting, and aesthetics in general, just to make the game more readable.
That is odd. I was playing in the browser. Not sure if I can do a windows application. With the time frame, the aesthetics being lack luster makes sense. Maybe some small textures on the walls to indicate the difference between left and right, like a torch texture or something just to make it different so when I'm looking around so it's easy to orient myself. I'll try the game again though since you said you didn't have problems before.
