Sure! Here's a simple implementation of a Touhou shoot 'em up game using HTML, JavaScript, and pictograms:
In this game, you control a player character represented by a pictogram moving horizontally with the arrow keys. Pressing the spacebar shoots bullets from the player character. The game loop continuously redraws the canvas and moves the player and bullets accordingly.
Please note that you'll need to replace `"emozi_all/player.png"` and `"emozi_apple.png"` with the actual image paths to the pictograms you want to use for the player and bullets.
Hope you enjoy playing the game!
