Hey, I didn't have a controller at hand so I probably didn't get the whole experience. It's a fun premise, a cat with a jetpack shooting bees and collecting cans of tuna. What's the lore? ;-)
I was able to mostly stay on the ground (so, not using any jet fuel) and quickly shoot the occasional bee. Until I was betrayed by the cat's collider, which seems to not adjust to the sprite's smaller height when on the ground.
Adding a "quit game" functionality to hitting Esc is a very low effort thing to add in order to make the whole experience a bit more polished ;-)
