I like the red-orange colour and the pixel graphics a ton. Sadly I found that there are some places tile gaps every eight pixel art pixels we very notable. I also found that in rare cases click on the player made the slime jump not light a torch. I think that bug was from click just before the slime stopped moving. You could solve this by allowing the action being done to change as the mouse moves around the screen. When the action is ready to be done, whatever is currently being done will be done. Also, I got stuck in a wall twice, though I could easily escape.
