Bug fix on April 4th

Bug Correction 1. Fixed a bug where players would be blocked by boxes after being defeated and retried in a sewer battle 2. Fixed a bug in the 1st floor bedroom during wartime where the health was 0 and the boss grabbed it, pressing the z or x button had no response. 3. The save and read file logic has been modified. Players can now choose 'Continue Game' in the title interface. The default is to read the 1st save. Please try to save the save to the 1st as much as possible. Other saves can also be used normally, but if the player's latest save is not number 1, other saves will not be displayed correctly. (Can be used, but without artistic effect, appears empty) 4. Reduced the attack range of ordinary variants and increased the crowbar attack range of milk tea. 5. Added gold coins obtained by killing ordinary variants. 6. Start with 7 bullets, now the bullets have become more abundant. 7. There are hidden items in the map. Please press Z more to investigate strange places. 8. Pressing F1 will provide a settings interface in the upper left corner, where you can customize the buttons. 9. Added playback speed for all text. The next problem to be solved 1. Occasionally, when opening the archive, it may get stuck and the interface may not pop up, with unknown reasons. 2. When closing the save, players will automatically attack with a pistol, wasting a precious round of ammunition. The attack judgment of the crowbar seems too large, and we are considering weakening it.
