Sure! Here's an example of a simple game where you can shoot aliens in space while controlling a ship. It's implemented as a single HTML file and contains JavaScript enclosed in script tags. The game will be playable assuming smartphone operation. I'll use pictograms to represent the game elements.
To make this game work, you'll need to replace the placeholders for the ship and alien images (`emozi_all/game.png` and `emozi_all/alien.png`) with your own image files or find appropriate pictogram images.
The game allows you to control the ship's movement using the left and right arrow keys on your smartphone. Shoot lasers at the falling aliens, and if you hit them, they will be destroyed. The game runs in a loop, continuously creating new aliens and moving them downwards. Enjoy shooting aliens in space!
