Woo, achievement! I worked on the game Bloodlust. I kinda regret not being the one to upload it though x.x If only because it's nice seeing the little tag of what one submitted. I'm sure there's a way to have multiple accounts marked as the developer? Not familiar with itch though.
Whoever submitted the game can include you as an "author", like I am in this game: https://petersome.itch.io/santas-jam . Altough I'm not sure if Itch will show the game's thumbnail below your profile pic.
