Sure! Here's a simple game that you can play, implemented as a single HTML file with JavaScript. It uses pictograms and can be played on a smartphone.
This game consists of a sky and a sea. Initially, there's a lion in the sky and a bird in the sea represented by pictograms. When you tap/click on the lion, it moves to the sea (the sky disappears). Similarly, when you tap/click on the bird, it moves to the sky (the sea disappears). The game can be played by tapping/clicking on the lion or the bird to switch their positions.
