There should've been a visual indicator of which crate is being controlled. The breakable floor mechanic was unintuitive. Was it time based, or if a crate is filled, or number of times crossed? Not sure?? How many times could a crate fall in and not die? The click active crate to switch to the inactive crate system was really hard to figure out when I tried blind. The art was cute, and I did enjoy the puzzles.
