This was really fun to play! I liked moving around the map and quickly selecting a path through the hexagons. I ended up playing this for a while. The sound effects and music were nice too.
Do you die if you take too long? I tried playing to let the tail catch up and snatch up the bonuses. Having the tail completely catch up and having no empty cells didn't immediately end the game sometimes. At other times, I'd get game over when playing like this even though I had a valid move.
For me, the text size was a bit small, but I can see how larger text could also clutter the screen.
