I’ll check this out in a bit, but you can drastically reduce the file size of this game with just a few minutes’ work. If you use a tool like XnConvert to change all of the images from .png to .webp you can reduce the total size to ~6% of what it is currently (I’ve dropped it from 726MB to 46MB).
All you have to do is add the images folder to the input tab, then copy these settings in the output tab:
The maximum cores will depend on your CPU, and the extra panel is from the format settings. Then with the code you just run a find + replace of all references to .png to .webp and everything will work.
As a point of comparison, here’s the title card before and after conversion:
I find the
.webp version to be slightly warmer, but otherwise identical. Itch has a 1GB upload limit iirc so if you add much more to the game you’ll have to host it elsewhere. With this your game could have 20x the images and still be uploaded to Itch.
