Thanks!
You are right about trying to center the mouse, but I'm having issues with it. I might have to put a "click here" button in the middle or something to make sure it doesn't go wonky.
I tried using the SetRaw mouse thing, but it just doesn't want to behave when exported to HTML5.
Psy, the music is pretty cutesy-- it's licensed from Audioblocks (as are the sounds); a recommended site. I'm a video/multimedia producer, so I kinda have this licensed just sitting here in the winter because I only work in the summer, so might as well use it for something fun, lol.
I spent a few hours yesterday learning Spriter Pro, and today I'm going to learn how to use that in AGK-- like swapping out sprites, pieces, controlling bones, etc. Gonna be fun (yes, I know, I have a weird definition of fun, lol)!
