This was fun.
I think if the pickles were programmed to spawn in 3s so if i jump at the right time I can get my health back.
I was also unsure why I would ever move down it would only ever kill me? I personally would of changed it to the W key. That way you could move increase your upward velocity mid air to jump at different angles. That way you could set up the pickles to spawn in 3s at different angles presenting more of a skill based experience.
That being said the animation for the cat was really good and the art style was cohesive. Well done!
