Well, uh, that's $136.34 in revenue that I don't have on Itch - I have a grand total of $0.00. So, hey, that's at least one person here that you're getting paid more than! Gotta count the small blessings, I guess!
Honestly though, it's hard to get noticed when the platform's flooded with other games. You'll need to stand out - and you might probably want to start by making your game covers look more attractive imo. People won't know how good our coding and gameplay are if they won't even click on the game cover to take a look because our game doesn't look as nicely designed as the others lined up next to it. That's what competition is.
If you're looking at other developers' pages and seeing that they're getting ratings and comments, why not look at how they've designed their pages, game covers and where they've been promoting? You can learn a lot from that. I periodically look up popular games and check their pages and covers out. I'd look at the colors and fonts they're using and how they're describing themselves in their profile pages.
Anyway, try not to let your experience on Itch deter you from your passion if engineering is really what you want to do. Sure, you won't be able to code the stuff you want, the way you want and there are numerous death marches along the road, but I'd say software engineering pays bills and you might meet some good bros there if you maintain a good attitude.
As for game design... you can give it a try as a career, but I've heard that it's extremely saturated. Still, nothing ventured, nothing gained.
Good luck!
