A horizontal jumping game, each level is basically a screen-sized map, you need to find the key, then find the exit and enter to complete a small level.
All the cards share the initial 8 lives, and after all of them die, they will restart from the first level. However, the middle and late stages can pick up the medical box in the scene as an extra life consumption, but overall it is still extremely insufficient.
The difficulty of the game is that there will be some traps/enemies in different states in the scene, which cannot be killed or die if they are encountered. Some attacks are very frequent or the movement trajectory is more unpredictable.
In addition, there will be levels similar to BOSS battles in the game. You need to step on the buttons that can be used alternately on the left and right sides to shoot missiles to attack the BOSS.
