After collecting a lot of feedback, I've improved the game!

Here are the changes.

- remapped the location of some buttons. It includes:

         - Crouch (left shift, D, down arrow key )

         - Attack (F, left click)

         - Special Attack (E, right click)

         - Slow Motion (left ctrl)

- A bug that cause the jump sound effect to play even when you are already jumping in the air

- Background music for boss fighting!

- The old slow motion system requires you to hold the keyboard button to stay at slow motion mode, now you only have to press left control once to toggle the mode.

- Changed some else if code to switch code.

- Poison ball can now one shot squirrels.

- Improvement of grammar 

- Added a discord button to make people join my discord server on the main menu.

- A number in the health bar.

- Turned on vsync

- Some slow motion bugs.

- Made a stage selector.

-One cutscene added.

Enjoy!
