thanks fortrying out the game dude, and about that boss you are right the levels are as unfinished as the whole game :/ sadly I've been unable to keep making it.
About that bug on the boss when you are fast, yeah I think I got a patch on that the last time I was programming, I made it so as if you got to a certain distance from him, he'll catch up quick. But as for now the project is in stand-by.
