Sure! Here's a simple game where you have to collect 5 objects while hiding from a monster. The game gets progressively harder every five nights. It's designed for smartphone operation and uses pictograms as requested. Note that this is a basic implementation and you can extend it further to make it more enjoyable.
To play the game, simply copy the code above into a new HTML file and open it in a web browser on your smartphone or computer. Use arrow keys to move the player and collect objects while avoiding the monster. You win when you collect all 5 objects, and you lose if the monster catches you. Every five nights, the game becomes harder with more objects to collect and a faster monster. Good luck!
