Oh well, sure.
- Playing on Itch.io web embed, most recent Chrome verion.
- About 2-4 GBs of avg RAM free.
- Not much on the CPU side, stays by 1GHz 25-30% load before loading the game.
- Built-in GPU, Lower than OpenGL 3.0 though.
In other words, the game just swallows resources when trying to render everything.
Maybe tune down the lighting and effects?
