Another small update. Now with smooth transitions between tiles and a basic minimap. Almost done with the maze navigation code, the only thing missing it a second layer representing walls not directly in the player's path (you can see this issue around corners sometimes). After I figure that out, next step will be populating the maze with monsters, traps, locked doors and loot. None of it interactive yet... that will come later.
Also, currently you can't walk backwards, which is kind of a pain, but it saves me the trouble of playing the tiles animations backwards. I'll probably add that at some bonus round in the future.
