Wall Climbing exploit

[orangetriangle]

The following pieces can climb walls: while holding left, repeatedly rotate CW.

[]         [][]         []           []  
[][][][]     [][][]   [][][][]   [][]  []

[]  []     ()    ()       [][]         []
  []  []     ()()     [][]       [][][]

The following piece can climb walls: while holding right, repeatedly rotate CCW, CCW, 180 in that order.

For all pieces made of square brackets in the diagrams above, the mirror-reverse technique also works.

I do know that some pieces can wall-climb. Fixing this wouldn't be easy. In fact, given certain design goals, it might not even be possible to prevent wall-climbing.

That said, I addressed the symptoms of wall-climbing already. There are two main benefits to wall-climbing in a typical stacker game; 1) Farming soft-drop points, and 2) Stalling indefinitely.

You can't farm soft-drop points because you are limited to gaining 25 minoes' distance worth of soft drop points per piece. This is done specifically to combat wall-climbing.

Stalling indefinitely is still possible. However, I don't think it's really an issue in a single-player game. The main game mode specifically rewards taking your time to make the best possible move, and I don't mind if you find a way to get more time to do that. All other game modes specifically reward speed, so stalling is a non-issue. Should I ever implement multiplayer, I will take steps to prevent stalling indefinitely.

With all of that said, I am certainly open to suggestions for better kicktables. My design goals were as follows:

-Kicktables should be permissive enough; if it looks like a tuck should work, it should have a decent chance of working. -Kicktables should not be too permissive. ASC, for example, is too permissive. I could have used that kicktable if I wanted. I didn't. -This T-spin quadruple should work (as well as a similar kick for the J/L pentominoes): https://twitter.com/Manabender/status/1369366286652874759?s=20 -Generally, maintain the goals of SRS: Allow pieces to rotate even if the natural rotation is obstructed, and allow "tall" pieces to kick out of a small trench.
