This is Circle simulator. So, you catch the yellow ball. Every time you do, your score goes up. If you don't catch the yellow ball in time, it fades away and is harder to find it. You loose your points if you touch the walls of the maze thingy so be careful.
Credit to @Teetee_is_cute2 for the original. Things changed: 1. The player is a square 2. Backgound is stars 3. Two more mazes 4. Maze is slime 5. Can't go through maze (well, mostly). Comment your score if you want to! :D
