Hey this is my site www.gamedeveloperstudio.com I’ve got an absolute ton of 2d assets available there are some freebies but most are paid but the prices are extremely affordable. I think you will be surprised!
It’s also all my own work so almost all the assets on the site are in one style allowing you to create not just protypes but produce and release whole games.
Sadly it never appears on any of these lists so I’m guessing not many people know of it!
Please check it out!
