I saw the game, downloaded the game, lauch the game, and got 5 fps. this game is not at all optimize for weaker systems, i hope the developer optimize.
Hey! I just tested on an old laptop out of curiosity and it looks like the screen scaling code doesn't always run (and if it doesn't you'll get really bad FPS), I'll look into it, thanks for flagging it!
If you start the build a second time, you might be lucky. You should see a pixelated effect on the screen.
