|Ability||Blocking the player|
Glass appears as a green hard block with light green stripes as light details. Over its four corners can be seen dark-coloured nails holding them in place.
The glass acts as a hard structure which prevents the net from moving through it. If a kitten falls off through it, the kitten's colour turns altered by the green of the glass. The net, in attempt of moving inside the parts where the glass has been placed will remain at the edges causing the player to be unable to catch the kittens in the very moment they're fallling.
Sometimes, glass appears as a large block covering most of the screen or fused with the metal plates.
