Slow project

making a new (serious) game, and I understand there are a lot of complicated things, but it’s running slowly. the large grid on the first frame has no intentions on a delay, yet at least for me there’s a half-second or so delay in showing up. placing blocks is also a bit slow.

It seems to be slowed down by the amount of grid. If you change it to a smaller amount, it won’t lag as much.
