Farting Astrounaut

Project that I am developing to create a game being noob; meanwhile I will be posting progress on short tutorials on this channel.
You can download complete project here.
to play:

WASD - move
SPACE - Jump
E - Fart 

(tried with joypad but it's not working properly with Itch.Io HTML; you have to use keyboards)

At the moment I have not developed the start screen, nor added audio, nor have I made the transition animations between levels; There is no game over either - even when the oxygen (green bar) runs out.
