GIMP magic!
I took a little time to create an example GIF of the lava effect across the map.

I hope it works! Apparently, you have to click on it
Oh well. Was going to add a logo but that is time consuming and I should be spending that time writing the code so I can come back and polish up some of the sprites at the end! THEN maybe do some media stuff! Priorities!
I’ve actually decided I am going to attempt Dart and StageXL. It shouldn’t be too hard to just get the game going that way. Using Phaser would mean making a few more decisions surrounding javascript and I just like that Dart handles all that for me. It’s also an excuse to practice Dart more.
