I am really sorry having a snake this fast ruined some of the intended gameplay. Sadly I didn't have time (nor a person) to playtest it, thus I set the difficulty too high up... I totally agree that there a many ways to improve the learming curve. I will not make this mistake another time.
Nonetheless, I'm glad you could still appreciate the main idea behind it. I really do need to improve my execution the next time if I want to win. :P
