W/A/S/D to move H to change the size of the grid / strength of the light F to switch between flashlight and candle B to toggle the border -> If you walk to the side of the grid you stop / loop around. The red outline just indicates, that the border is on. If you change the size of the grid, double-click the green flag. Otherwise it might bug out the project. Don't have the size up to 200 and the x/y length at a high amount at the same time... that might also bug out the project.
This took longer than it should have. I really like how the candle turned out. I wanted to create a random generating floor pattern, but i didn't have the strength to do it...
