Sure! Here's an example of a simple game that meets your requirements. It involves using bug sprays to defeat spiders and the spider king:
In this game, you control a player (represented by a blue square) using the left and right arrow keys. The objective is to shoot bug sprays (green rectangles) at the spiders (red circles) and the spider king (purple circle). If a bug spray hits a spider, it is defeated, and the score increases. If you defeat all the spiders, you win the game. However, if a spider or the spider king collides with the player, the game is over.
You can use this code as a starting point and customize it further to add additional features, levels, or graphics using pictograms if desired.
