Survival mode changes

The flow experience of survival mode is not very strong. Some adjustments are currently made:
1. It is more difficult to recharge the survival mode recovery button, and it is easier for players to make difficult choices in the early stage. This will increase the difficulty of survival mode.
2. Survival mode will also get points when charging, which will give you a lot of extra points, making the score on the new difficulty more consistent with the old difficulty.
