Motivation + Reward Systems + Feedback
Touhou Series is a dynamic-heavy shooting game. When I play this game, it's the bullet formation that attracts me--- beautiful and brutal. I have mentioned that all the bullet formation are generated from mathematical calculation. Challenge Touhou is like solving math problems that you know how to solve it at first, but the problems keep adding variables to preventing you from solving them.

Like typical shooting game, the game rewards you with point based on your performance. When you get enough point or defeat a certain boss, you will get a life-up item. On story-wise, beat the game on normal difficulty without any continue will unlock the extra mode, which is a stage in Lunatic difficulty with no continue available---a brand new challenge for players. The best I can do so far is probably hard mode clear with two continues.
All the player's info is displayed at the right side of the screen: high score, player score, life, power, and title. Player can get more feedback from the game in visual and audio, too. Player get to hear the sound effect when destroying enemies, getting power-up, using bomb, and getting hit. When fighting a boss, theme music of the boss sync with the beginning of the battle, which give out the intensity within the boss. One player friendly feedback feature is the location of the boss is shown at the bottom of the screen. Without it, players need to look up and confirm the location of the boss while trying to dodge all the bullets.
