To echo what your saying and add a bit, it seems to me Godot would be a great idea.
Given OP has already stepped away from development once, I think a more universal game engine rather than a custom engine would be beneficial.
Also, I suspect, there are a lot more Godot developers compared to people who are willing to take time to understand and develop a custom game engine.
I’m not familiar with deploying custom code/packages/programs on a multitude of systems, but from the Godot updates, my understanding is that, its clicking a box. I feel that multiple systems are a nontrivial hurdle that could be avoided via Godot.
Last thing off the top of my head is that I recall one of the Godot tutorials is developing a pixel art fighting game. That seems like it would be an easy way to boot strap the game’s development.
Regardless, I think a FOSS brawler game is a great idea. Good luck with development and I look forward to checking it out when its available.
