2D Platformer: Astro's Adventure

This is my 2D Platformer project. 

Here are my following modifications:

1. Aesthetics- Changed the music, redesigned levels, and also included additional credits and provided instructions.
2. Difficulty - every level gets harder (eg. more enemies, enemies can move faster), 
3. Player Boost -  every level, the player becomes faster, and jump power increases

Disclaimer: This project was created on a windows machine, so the macOS version has not been tested.
