Features:

• Sets spawn height to (board height) + 8 when active
• When inactive, spawn height cannot be increased but it can still decrease using the previous rule, down to a minimum of 20 blocks,

one thing: don't use non-5N-font-size (I saw a 26)
it will cause a new font object created, occupying more memory

done

Very cool, but it looks like the infinite height mode doesn't move the camera enough, so only 3 blocks of space can be seen. The pieces also drop that low.

not sure what you mean by "the pieces also drop that low". they spawn 8 blocks above the highest mino of the stack

In the video, it shows that pieces only drop a block from the height

that's the ghost piece... 💀
