Super Space-Stronaut

This is a game with all the assets from the tutorial I have learned. I have made some modifications based on the original one. Here is the list of modifications:

1. Added a 'Continue' button in the menu: The 'Continue' button will load the highest level you have reached.
2. Modified the Level Selection scene: It will now only display the levels that you have unlocked.
3. Added a flicker effect whenever the player gets damaged.
4. Introduced a new Boss enemy.
5. Created a Boss fight scene.
6. Completed all the functionality for the buttons (except credits and instructions)
