My first few plays, I didn't realize I could use the mirror. After closing the eye that's hard to get to and discovering that it didn't open the door, I thought I was gonna have to quit having done all that work for nothing. But I finally discovered that there was another eye.
People are giving you a lot of grief about the controls, but I think you did the best you could. Allowing both WASD and arrow keys makes it better than a lot of games right off the bat. Maybe one of the options (e.g. WASD) could work like the tank controls and other could be fixed directions.
The camera angles change at the right times to give you plenty of warning about what's around you. The enemy AI has some good pathfinding. It's clear that you went through a lot of effort to make this as good and convenient as possible. I got a bit of a Diablo vibe with the dark temple and everything.
The most legitimate complaint is the speed, though. You should definitely move faster. You say this is a very short game, but the character speed pads the length a great deal.
I look forward to more of your work.
