1. Add 33 pieces of achievement, plus the original 6, which add up to 39 at present, and will continue to be expanded later.
2. Add "Data in this Round" interface so that players can view the current progress of the game and get the hang of achievement accomplishment progress.
3. Add "Ult", which can be released by pressing Number Key 1 or 2 at the cost of certain HP.
4. Add the option of "Restart from Stage 10/20" after the game is over, instead of starting from Stage 1 every time, boosting the game pace and making players easier to accomplish the achievement goals.
5. By adding the concept of "Achievement Points (APs)", players can obtain corresponding APs by completing achievements of various difficulties, and the number of APs is positively related to the completion difficulty, i.e. the higher the difficulty, the more APs will be granted.
6. Only by obtaining certain APs can you choose to restart the game from Stage 10 or Stage 20 after the game is over.
