The game is nice and the puzzle fun and well though. I kinda broke the game tho. You can move the camera across locked area. the control doesn't fell smooth without diagonal and the mouse to get item was kinda broken with the camera glitch i found. You still have a good base to work with.
How to do the bug
For the glitch all you have to do is moving to a room and falling back before the camera finished moving. The camera will go to the room that the player has already leave to the room before the camera move. And by repeating we can move the camera far, even out of bound. With some timing we can do that both horizontaly and verticaly
