Hey, I checked your game :)
- outstanding dungeon music, so fit for such a game :)
- I liked the graphics concept
- movement seems a bit weird though; I felt the turning takes a lot more time than usual and one time it took like 5 seconds to turn. It also felt that you really move slower, perhaps choosing another field-of-view?
- great shaking effect, definitely a threatening dungeon! I wish it wasn't used against you on movement :)
- nice concept in battle mechanics; if you miss one or three actions, you're simply dead :) nice and efficient.
- it would be better if the "background" color on monsters was removed as well and monsters were placed a bit below in Y-axis, like walking the ground (except beholder of course).
- when you enter a battle, you can't turn left or right to face the monster :(
- I lost some battles later but then I couldn't exit from this "Game Over :(" screen.
Overall, a nice crawling experience, with great music and nice ideas :) Just need more time to fine-tune the experience :)
