So use arrow keys or WAD to move, and go close to the orange cat to listen to what he is saying and I remixed Rosyda's project so I added 3 things: Deleted the pollution to make levels easier, added ground that is safe to walk on where the poison was deleted and added a way to skip the levels: by dragging the diamond down to the sprite and it skips the level and the diamond goes back to its new needed place in the new level.
All by rosyda but i made the diamond draggable and i took away the pollution.
