Inspired by “Stacker” wave. In this wave, chickens and barriers forming tetris pieces (no they won’t be stacked each other), sometimes they will do a 90 degree CW/CCW
(C blocks are chickens, grey objects are destroyable barriers)
These pieces on image are T Z O I pieces (L S J pieces are also included for this wave idea)
There will be 10 pieces, 2 pieces will be on screen.
(Edit #1: I much perfer once kind of chicken every piece, not multiple)
