Flower Cat
At the "Cat Base" menu, drag the handle of the door to the right to open it. You will see red-eyed cats and hear meowing. Repeatedly do this until a message appears stating that you have unlocked Flower Cat. Go to "Special Cats" to access it. Flower Cat attacks well and has a slight chance of stopping black enemies.
Restore Cat Energy
Cat Energy limits how often you can play and is restored over time. To refill it instant, advance the time on your device. Afterwards, set the time back to its correct value.
Upgrades
To upgrade cats, save experience points and use them to level up. You will not be able to see the specific improvements, but will notice them during battles. To earn more experience points, upgrade the Cat Study. This will allow you to earn more experience in each level. Upgrading the Cat Cannon will increase its range, damage and charge speed. You can use it after completing its charge to hit every cat that is behind the pink dotted line. To be able to play longer, upgrade Cat Energy. Cents will allow you to summon more cats during battles. To get more Cents faster, upgrade the Generator.
