Hello there! Thanks for your appreciations!
I'm trully glad you liked the way I managed the limitation / theme, I've really tried my hardest to complete this game. I agree that the background loop is quite short, sorry! I guess I just runned out of creativity when composing the theme. Hopefully I'll change that after the jam ends. Thanks for the support!
Also, yesterday I played your game. It was probably the jam game I stayed the longest playing, really cool concept! I ran out of fuel all the time but meh, pretty nice game. I really appreciate your work!
