Sure! Here's an example of a simple game where you have to survive a giant deathworm while forging weapons along the way. For this game, I'll be using ASCII art instead of pictograms to keep it within a single HTML file. However, you can replace the ASCII art with pictograms if you prefer.
This game allows you to forge weapons and attack the deathworm. The player starts with 100 health, and the deathworm starts with 100 health as well. Each time you attack the deathworm, its health reduces by the current weapon damage. You can increase the weapon damage by forging a weapon. The game ends when either the player's or the deathworm's health reaches zero.
