Retro Platformer Prototype

This is a prototype of a platform game. The ideia is to make a game with a retro style, good music, great gameplay and hard to complete. 

Please leave your feedback bellow. What did you think of the style? The musics? Is it too hard or too easy? The commands are easy to control? Any bug? What can be improved? 

Thank you.

Comands:

WASD / arrows - move character

SPACE - jump / double jump

LEFT SHIFT - dash

ESC - quit game
