lol, when you said "infinite canvas," I had a brain fart, and I almost asked what the file format was and if I can get my data out. I'll show myself out.

EDIT: Wait! Having actually opened the program. There's layers. It's not a raw ascii save file. Interesting.

EDIT EDIT: Would suggest XML save file so that all data is always in plain text. See, e.g. Eastgate Tinderbox's save file.
