This is a 2D Sonic platformer, where your goal indeed is to go up The game is one single huge level for you to clear, with areas of said level split into different zones Rings are sparce (you can hold only a single ring), there are no checkpoints, and you will most likely fall down a good few times
Oh, but don't worry, the game autosaves
If you're familiar with Getting Over It, Jump King, Only Up, Get to Work, all those sorta games, you know what to expect If not; expect to get frustrated and annoyed
