It is very difficult to play this game if you have an internal GPU, it runs at around 5-10 FPS. I literally can’t run this game on higher than low graphic settings without my computer turning into a jet engine. Because, to but it simply, my PC is a potato.
I have a few simple suggestions:
Reduce the amount of individual tiny squares there are, not everything needs to be incredibly detailed. you can use also textures instead of squares for detail.
Consider using a particle system instead of individual moving squares for spells, the dust circling around dust devils, and various other things.
And you could make all these be dependent on your graphics settings, of course.
