A game in a game! DifferGame is a minigame based on diep.io created in Geometry Dash v2.11!
In DIfferGame, your objective is to shoot various obstacles to get points while keeping your little ship(or is it a tank?) healthy! The level is about 4 mins long and even includes a boss fight at the end, good luck!
I also happen to be a mapper in Osu, and practicing mapping in other rhythm/music games as well!
