Rumble Studios./Bubble Gum Simulator

Bubble Gum Simulator is a simulator made by Runway Rumble, a popular development group that made multiple other popular games such as Mining Simulator. The main idea is to blow bubble gum until your 'bag' is full to get cash. You can upgrade your bag in the "Gum" tab in the shop menu, and you can upgrade how much bubble gum you get for clicking in the "Flavour" tab.

The bubble gum bubble you have can be used as a balloon, in the sense that you can jump higher and you can jump on clouds to get to special areas high in the sky. You can also upgrade your stats by opening eggs. Eggs contain pets ranging from common rarity, to ??? rarity which is commonly known as a legendary, which is very rare. Pets have three different stats.

There is the first one, bubbles. These will add on to how many bubbles you get for clicking, for example if you have one bubble per click, and your pet has +3 bubbles, you will now get 4 bubbles per one click. Then there's a coin multiplier, which will give you more coins when you pick up any amount of coins. The same thing is for gems, except you have to pick up gems to for the multiplier to apply. You can also get boosts with coins or gems in the rewards tab. These are essentially missions to get an extra reward. It will make a sound once the requirement of a mission is complete. The missions get harder gradually as you complete them.

Islands
There are five islands that are accessible via jumping on clouds, so you need to have a big bubble to be able to jump high enough to platform up the clouds. The clouds become more spaced apart the higher up you go.
