Can you add several types of perfect clear practice modes?

[dezhonger]

What feature do you want to suggest to the game?

For example, like PCO, Grace system,3×4 box, 4×4 box,5×4 box.. I know there are already two perfect clear modes, could you please separate them in detail?

This is definitely possible but idk where to put it in the map, it's already pretty crowded

[dezhonger]

I have an idea, like 10 lines, 40 lines, 100 lines, 1000 lines racing, in order of difficulty.

Unrelated ideas should go on a separate issue.

Line racing with perfect clear bases? Not bad but also not that interesting, got it.
