Click your Gobo to gain coins. When his bar reaches the end, you will also gain coins. Once you have enough, you can buy more Gobos from the shop. You can buy multiple Gobos, which will make the bar and the clicks give you more coins. Once you buy more Gobos, you can click them seperately and they have their own individual bar. If you have questions, ask in the comments! Press the down arrow to see more available Gobos. Try to save up enough to buy the Sophisticated Gobo! @cold_banana, my friend, helped me design this.
