BU is a fun game that is similar to Coreball. Shoot 10 red arrows at the green ball as it moves in a circle. Accurately aim to score points and progress to the next level. The following levels will be significantly more challenging because if you release the arrows and then hit another arrow on the orb, the game will be finished and you will have to start over. Improve your aiming abilities.
To win, you must design methods and accomplish missions as quickly as possible. The ball is blue, like our planet, and it rotates gently. In each level, you can solve problems. Experience 75 distinct levels; what experiences do you gain at these levels? Do not be hesitant to try different approaches until you find the one that works best for you.
