Level Avalanche is still built incorrectly. It has "WALL IS STOP", but no actual wall tiles. It has cliff tiles and "CLIFF IS NOT FALL" though, so that's probably what you meant.
Edit: Stardrop and Meteor Strike can be cheesed with "BELT IS S T A R IS FLAG". You can finish "S T A R" right next to a belt, and there's two turns before "FLAG IS WIN" is disrupted, exactly enough for belt to to star (and then flag).
