Optimizing game for lower size

Community

Just wondering what other people do to make the game size smaller. I found an app called PNG Gauntlet that I use to make the game images smaller not a bad app as it shrank the project folder from 14MB to 4MB without losing any quality of the images.

I think my worse habit is always using PNGs which can have a large size over JPGs

It is always a good idea to reduce assets (photos, video…) to the size you will use.
For example, if the size of the object in your project canvas is 64×64 (no zoom), shrink the original to 64×64.
However, keep a backup copy of the original, just in case.
