It's sad what you just explained, but that's the bad thing about developing ambitious games, that they end up being canceled due to inexperience in development, lack of time, budget and material, precarious situations, oversaturation in competence, engine limitations & tecnical problems, loss of talented team (especially due to layoffs that occurred between 2023 and 2024), all those problems together condemn a project to be in the limbo of development hell (I know because I'm living in the same situation).
By the way, what did you have planned if you managed to complete the game?
