I like the game.
The light effects give it a great feeling that you are in a confined space. It's also nice that you have to hurry but don't have to super-rush. My only issue gameplay wise was that on the fifth level, I noticed the pressure sensitive tiles on the floor (that shoot arrows?) but I didn't know what attacked me later on (same attack sfx so I'm assuming also arrows).
A few bugs and suggestions:
Can you change the keyboard controls? I saw that the "action tiles" can be clicked but that pressing a key afterwards didn't change the assigned keys.
Options page: the flame is right in front of the Back button. It's sort of visible and works when clicked from a functional point of view but visually it's obstructing.
When I went back to the Main menu (from Options), menu buttons/tiles/bricks didn't return to middle position. Even when going to Options screen then returning to Main menu, the same issue remained. Buttons worked fine though.
When starting a new game for the first time: Continue button should be disabled (e.g. darkened out) on the "START" screen since the player hasn't played any game yet.
Good luck!
