Sure! Here's a playable sample game that simulates a simple spider girl game using JavaScript. Please note that the game has been scaled down for simplicity.
Spider Girl Game
In this game, you control a spider girl (`blue` square) using the arrow keys on your smartphone. The objective is to catch the spiders (`red` circles) while avoiding colliding with the borders of the game window. Your score increases by 1 each time you catch a spider. The game will continuously update and display your score in the top left corner of the canvas.
