Pick an egg from the nest, that's your character for the run. Each level is a randomly generated map of enemies, loot, and farming pots. Seeds you collect can be planted mid-run and harvested into stronger crops. At the end of each level, a shop lets you spend your gold on new items or sell whatever's in your stomach.
The farming loop is the core gameplay: your inventory is your stomach. Everything you eat gives you passive stat boosts or effects, more bullets, faster fire rate, higher damage. Managing what you eat and when is the whole game.
Increase your power exponentially to keep up with the incremental difficulty of the mountain. Can you reach the top?
