Small update. I've been adding more stuff, and finally 100% completed the haunted castle level! It has ghosts, a boss fight, a cellar, a library, haunted torches... Lots of spooky things. However now that it is mostly completed, I'll probably move to other levels shortly. Either finish some existing ones or start on some new ones.
Other than that I don't have too much else to report, so enjoy some GIFs from the haunted castle level I mentioned!
