Very cute game! It reminds me that specific genre of girl games that were popular (not exactly sure what to call them? like those games like Devilish Hairdresser).
It did get a little frustrating on the last level cause sometimes it felt like they kept getting alerted every second + a lot of poor shots. But eventually, I got a good run and completed the game. (Luckily, the game is kind enough to not restart the runs from the very beginning!)
