We built this in a day in Godot 3.1, and then spent last couple days adding a new prestige mechanic, saving, etc. It's nothing fancy but its a great way to get experience shipping something on kongregate. We'd love any feedback or feature suggestions, though i suspect the nature of the game might limit it's scope potential! https://kongregate.com/games/Fluik/godot-number-goes-up
This is a remake of the idle incremental classic Number Go Up by Tyler Glaiel http://glaielgames.com/number/ which was built in Flash.
