The Shop is an integral part of Super Bomb Survival.
The shop can be accessed by opening the Menu and clicking the Shop button, or by walking to the Shop itself.
Once you do one of those 2 things, you are presented with a menu containing many options.
This menu contains Skills, Perks, Boosts, Gems, Gamepasses and the skill packs present in the current versions of the game.
The shop also has the Day / Night button near it, which is used to change from day to night and vice versa.
