Your goal is simple: Press the button. (Also click the Shop button to enter or exit the shop; and to buy things in the shop, click those buttons.)
I did not invent the clicker game, and this is a pretty simple one I made in an afternoon. It's my first game with actual music, which I think is nice. Comment if there are any bugs! I only tested this for a while, so if anything needs tweaking let me know. Music: Soundnoia by DjVi
