Numbers are approaching quietly. In the battlefield wrapped in tension and silence, the missile launch sound and impact sound resound. By targeting the number itself as identification information, we can realize a vast battlefield. Let's pursue simplicity and reality, let's open a new world of 3D shooting game. It is a 3D shooting game that no one has ever seen, which is very effective for brain training, stress relief, and mathematics learning etc. ---How to Play--- On the menu screen, select the type of question. If you select Addition (+), you will answer the question of addition. If you select Subtraction (-) you will answer the question of subtraction. When Random (+, -) is selected, the question of addition and the question of subtraction will be answered in random order. Please answer the question on the top of the game scene. Please answer the numbers that apply to the red sign "?". Then please find out the correct answer from the approaching numbers and tap it. A missile is fired towards the tapped position. Points will be added if the missile hit the correct number. The score will be displayed under the question. The more you hit the farther, the more points are added. If you did not hit the target even if you fired a missile, please correct the trajectory by slightly changing the touch of the fingertip. The missile held at the start is 100 shots. The rest of the missile is displayed below the score. You can also supply missiles. We need combat ability to quickly find answers, quickly discover and identify targets, quickly decide shooting, firing missiles quickly and hit. The theoretical maximum score without supply is 20000 points. But if you can exceed 10000 points, your combat ability is amazing! The result is represented by the score and the number of ★. ★ ★ ★ ★ ★ indicates that it exceeds 13000 points, ★ ★ ★ ★ indicates that it exceeds 10000 points, ★ ★ ★ indicates that it exceeds 7000 points, ★ ★ indicates that it exceeds 4000 points. ★ indicates that it exceeds 1000 points. Let 's keep trying to become a Five Star. When the numbers appear from the forest or emerge from the raised ground, if you can estimate the whole from the emerging part and quickly fire the missile, it will lead to a high score. But even if you try to defeat all the numbers without worrying about the score, you can enjoy it enough. It is addictive pleasure and leads to stress relief. However, please be careful not to be too addicted. ---To parents with young children--- This game is great for learning numbers and arithmetic. In order to be able to play even for young children, I made a screen friendly to the eyes and avoided flashy production. There is no limit on the time to answer, so the children can think carefully. Children can learn without getting tired. ---caution--- The volume was set small. Please be careful not to turn up the volume too much. ---Acknowledgments--- This game was made with Unity.
