Intel GPUs are really weak, I don't know if they will run anything well
They run my game really well. Even older ones from many years ago.
With the 0.13 alpha 7, where I found heaps better performance on Intel GPU compared to 0.10.5 and 0.12!
And they are the majority of the market, especially notebooks and low-end PCs that are supposed to handle 2D games well.
