That’s the problem with PC builds. Very few people actually download them. That’s why you will mostly find browser games in the jams. And considering that your game is 608 Mb in size, it’s even more off-putting for many people.
That’s why I decided to make all my jams browser-only, with low-poly assets and highly compressed textures. It takes a hit on the visuals, but as long as the game is fun, people don’t mind!
