We’ve got an idea of what we want for the mechanics, the story, the art style, the music, but we don’t have an idea of how to make it all possible.
The music we can compose and the art we can draw. The story has been mostly figured out already. Just the engine for this game is something we don’t know how to make. Then there’s the 3D models of which we have no experience making any and we don’t know how to make them look the way we want them to in the game.
We’ve been meaning to ask on other developers forums but have been afraid to since it is a weight gain game. The player’s character (and other characters) can gain weight and it’s a mechanic in the game. We were never sure how people would react to that. We even have a development license to make game for Nintendo consoles but Nintendo wants to see the finished game before giving us a license for the Switch and we need money to buy a dev kit even after that (we can get one for the 3DS and we have one for the Wii U but still).
