The result is a boss battle that, while not exactly epic, makes for a good final duel for the game. The boss fights like the second level boss from Stompy's Revenge, except I implemented a semi-set pattern of movements this time. The boss requires five hits to kill.
So yeah, I'll probably release the demo tomorrow or monday. I think anybody who has enjoyed the past demos of the game will really enjoy this final level.
After that, I have a bunch of stuff left to do on the game, just not level design. In a way I'm glad, because designing levels gets a little repetitive and boring after awhile, so it will be good to work on other parts of the game.
