THERE'S A CREDITS SECTION YOU FOOLS.
Also for legal reasons Ame has never accepted money to work on this game. Ever. In. Any. Form. Reborn is the most non profitable pokemon game in history. pls dont kill it before E19 nintendo.
Nah but like this is the answer, also agreed fuck budew.
I think Ame does like 50% and the main work (Story, most of the development) while everyone chips in with their free time and bug tessting and supplementary stuff. Not to discredit anyone in the credits I'm just spitballing because I assume they do a lot of stuff (I remember like 50 people helped out for the gen 7 sprites) but it's most of the supplementary materials like sprites, animations and ya know making sure the game doesn't crash when you catch a meowth. Also jan is in the credits for what they did I do not know but I assume they did spritework.
Straight from the readme file in Ep. 18.2
