Yay to new release! I'lll try this when I've time. (Although I think I actually finished the game already)

Just treat enemies as you would tiles. Even though they move around, they still have an absolute position that you can adjust according to the camera's x and y to draw onto the screen. It takes a bit to bend your mind around the concept, but once you get it it's actually quite simple ^^

Great game, but there is some bug....
I went to pipetown into the lower right house where you have to destroy a pipe.
and then i was in 'secret cave'
there were lots of arrows, i saved as using some needed to restart game, like that you are stuck
then there was some cave with treasures, in one of them there opend then a dialog that looked to me like the end dialog, in a other one was some random speach
EDIT: now i don't have my real saves

I don't remember which download, lol
i think it was the latest off this thread

But then i have to replay, lol

I'll just replay ^
