I haven't found a game yet which which implements that concept. The closest is probably Noita (https://noitagame.com/). But I would like an isometric view (or third-person view in 3d world) and the spells effects use some kind of particle animation within that world; as opposed as simple pixels in a 2d platformer.
I don't have a background in game development, so I don't know where to start. I'd like to discuss the idea and potentially have some devs build a prototype to build a prototype and see if it's actually fun to play with. How do I reach for studios and/or indie devs ? Are there good gamedevs forums for that? I am willing to pay for contracts to build some prototypes or fund a whole game if things are promising (let's say ranging from 50k to 1-2M).
