Nothing too too crazy, it's a serious mobile game that's supposed to help the players with living in a more sustainable, eco friendly way:
A simple 3D environment where you can do some simple customization (Terraforming terrain, putting down plants/rocks/other props, some animals): An extremely simplified version of Equilinox basically
Then a GUI that informs the player of the impact their real life actions have and challenges them to change something about it. Performing this challenge (Manually inputted) unlocks one more plant/rock/prop/animal.
I have a fair bit of experience with framework level game dev and the rendering stuff: At the very least I'd be able to setup the 3D environment rendering and UI rendering needed for this game with OpenGL. Anything beyond that would be new for me.
I've also already made a few serious mobile games (With way bigger scopes), but that was with Unity, so this is on a completely different level
The goal of making this game is not so much the game itself, but for the company to get experience with game development, and perhaps setting up the very very basics of software that can be expanded upon.
I realize that Silk.NET is just wrappers and bindings, for me that's exactly what makes it so appealing: Getting the ability to implement higher level concepts the way you want, getting control over that. The obvious downside being that building that takes an insane amount of effort, time and knowledge. But if it's feasible to setup the described game with Silk.NET within 9 months, then it's at least worth investigating that possibility.
