First attempt to put the game here. I made the game for a long time, but decided to try to post it here to see how everything works here.

Objective: to move the ball from the blue corner to the red one.
You can pass several times, the shortest time is recorded.
The big arrows turn the maze. The circle in the center blocks gravity. The arrows at the bottom right change the opacity of the walls. Left buttons: exit and start over.
