Hi Jorava,
Thanks for your honest feedback! I greatly appreciate that! :D
About the music, it is really a small fix, but we will do it after the voting phase. Also, we planned at least 5 obstacles, but could not make on time (taking into consideration bug fixes and art production related to them).
For now, I will just ask for you to stay tuned. We are planning a updated version regarding community's feedback, might hit after the JAM voting is over. ;)
