This is a single level platformer built in Godot leveraging some amount of GDScript. As I am not an artist or musician myself all of those assets come from the community of artists that make their assets available for use on the Internet.
Here is the list of resources which were leveraged for this project:
Elthen's Pixel Art Shop (Patreon)
Pixel Frog Kings and Pigs Pixel Adventure 1 Pixel Adventure 2
The Essential Retro Video Game Sound Effects Collection by SubspaceAudio
“Mutant Jackrabbit”, from PlayOnLoop.com
"The Precipice of Victory" Composed by Jonathan Shaw (www.jshaw.co.uk)
