An interesting math game. If you are on computer, you can use arrow keys or A and D to move. If you are on mobile, you can tap the left and right sides of the screen to move. You start with your value at 75. Boxes fall on you and each has a value at the top. If you touch a box, its value will be added to your total, but if you get below 50 or above 100, you lose. Your score is the number of rounds pass. you can also change your character at the bottom right on the menu.
You can play with multiple people if you keep your score counted and have multiple people play, and whoever has the highest score wins. Last character is "the eight by eight" (which is actually a 10x10)
