Sunnies will periodically release deadly beams of energy. Touching the beams will kill catgirl instantly.
Sunnies has a reflective shield that deflects catgirl's normal bullets. These bullets will ricochet and hurt catgirl.
When one sunny is slain, the other sunnies become enraged.
After killing an orange, catgirl gains one bullet. Be careful not to shoot at a sunny (ricochet).
There are no golden hearts on this floor, meaning catgirl cannot reload her gun.
When catgirl depletes her ammo, her blood bullets are effective against both oranges and sunnies.
The level can be completed by killing 100 oranges, by killing two sunnies or by killing sunkensunny.
Sunnies do not begin their attacks until the player starts moving (the timer starts). If catgirl shoots a blood bullet at a sunny without starting the timer, sunkensunny is summoned as an anti-cheat measure.
