0.5.2 - Some bug fix

Thanks to everyone for the feedback. I’ve fixed several issues and made some change:

1. Fixed game freezing when health was restored upon death (e.g., natural recovery in Easy Mode, defeating a boss, etc.).
2. Fixed an animation bug that occurred when saving during attacks.
3. Fixed the hidden virtual joystick being trigger on non–touch devices.
4. Fixed the “cinematic effect” not disappearing after loading game.
5. Fixed respawn point appearing on unstable blocks.
6. Fixed pixel error in the snow mountain background.
7. Watermelon seeds can no longer damage breakable barrier.
8. Improved the detection logic for watermelon seed hiting mech ball.
9. On the web platform, removed options that are unavailable when running in a browser.
