Wow, I'm feeling flustered here!
I'm glad to see so much enthusiasm!
You bet I'll getting this game complete one way or another!
Also, as a special bonus, don't know if you noticed, there are special items in each stage that pretty much made the whole demo game easier, BUT are really helpful to fight the extra bosses AND the secret boss (which is hidden in the last room somewhere....)
Hope you have fun with that while I prepare the next release!
