[1.0.4] Option to skip first map + fullscreen fix (全屏修复)

Hello there!

Changes:

• Added option to skip first map once you finish it for the first time
• Fixed issue with fullscreen not working properly (quick-patched it 11h ago, now officially)

There was one person who was very upset about fullscreen not working. Instead of reaching out to let me know and help fixing quickly, decided to throw shit at me. Hope you are reading this, despite not being written in Chinese. Have a good day. Chill a bit.
