About this game

"Notification Monster" is a unique idle and monster-collecting game that utilizes your smartphone's notification feature!
Those notifications you usually swipe away without a second thought transform into exciting signals that advance the game!

🌟 Game Features 🌟

🥚 Send monsters out to explore! Dispatch the monsters you've befriended on expeditions.
After a set amount of time, you'll receive a "return notification" from your monster! Tap the notification to open the app and claim the fruits of their exploration—like energy and new eggs.
The game progresses smoothly while you're away!

🐣 Collect energy and hatch eggs! Use the energy gathered during expeditions to nurture and hatch your stored eggs.
From cute critters to cool beasts, you won't know what kind of monster will hatch until the moment it arrives!

📖 Aim to complete the Monsterpedia! A wide variety of unique monsters appear, ranging from Normal (N) and Rare (R) to Super Rare (SR)!
Find your favorites and aim to fill out your entire collection.

⚔️ Intense boss battles! Occasionally, a mighty boss monster will attack, triggering a "Boss Appearance Notification"!
Open the game and attack immediately after receiving the notification to trigger an "Emergency Bonus" that doubles your damage!
Defeat the boss using the monsters you've raised.
If you succeed, you'll earn an egg containing an ultra-powerful SSR monster!
