I'm on windows 10. I have an old but still decent GPU (NVIDIA GTX 650) (I can run blender no problem) It might be a shader that is performing heavy operation many times but I can't be sure.

I don’t use shaders here. The game doesn’t use GPU. Did you have background tasks or a weak CPU?
I just played through to level 5 without lag on a 7th gen Intel using Win10 and Edge. It was using 100% CPU, so room to optimise there, but better than going idle I suppose!
I’ve gotten to level 40 on my laptop; where I wouldn’t hear the fan for the sounds in my brain.
I’ve documented the known bugs now, maybe you conflated “lag” with one of them?
