Sure, here's a simple game that meets your requirements. It's a survival game where you have to survive for 100 days by avoiding monsters and collecting items from the water. You have 10 seconds until you drown, but you can use the collected items to buy stuff to help you survive longer. The game is designed for smartphone operation and uses pictograms.
Note: This is a simplified text-based version without actual pictograms due to the limitations of the text-based interface. You can enhance it with actual pictograms and further graphics if you want.
In this game, the day-night cycle updates every second. You start with 10 seconds each day, and if you run out of time, the game is over. You can collect items by tapping on the screen, and every collected item increases the count. You can also buy a life jacket using 10 collected items. The game will display the current day, time left, collected items, and the option to buy a life jacket.
Feel free to enhance this game with more features, graphics, and interactive elements as per your requirements.
