All sounds good. by the way, I'm uploading a fresh version right now. This one includes the ability to upload 0-4 tile set frames so each tile can be animated as well ( though only 1 tile set is actually needed ). It's a little cumbersome to use with all those frames etc, but it works too.
Yes, when you are happy with whatever tile sets you do, you'll have to send them to me as files so I can include them in the build/published version.
The latest version is now available at https://itch.io/jam/alchemy-jam-7/rate/4154591 and it includes the multiple tile sheet animation things -- if someone locally provides these sheets, their game will feature the animated tile sets. If you do animated tiles this way and after you send those to me, I'll build those into the default game most likely. Wow this should be looking really nice I'm guessing with your art. The images might be blurred because I have a zoom scale on the draw ( they are very tiny at 32x32 otherwise ). You can use mouse wheel in game to adjust the zoom.
