Currently there's only the wolf with more enemies planned for future updates. The cracks in the walls are just there to break the visuals up a bit with more wall types. There are ideas I could do with the cracked walls but all of them are just concepts that aren't getting implemented soon. Also the detail for textures are hard to do since it's a 1 bit game (Exclusively black or white) and making the tilemap simpler just means that the player can see more thing more clearly faster. The next update will address more issues with the game while adding more on top.
Anyhow, thanks for the feedback and thanks for playing.
Happy plundering!
