Easy strategy to beat the game:
Choose one direction and keep pressing that arrow key with the right duration and interval to stay out of the center. Don't alternate with the other direction, because then you'll gain momentum and get too far away. Make small movements in other directions as necessary to hit threats or get powerups.
Powerups seem to remain indefinitely, so only get them when you need them.
I only got hit two or three times throughout levels 5-10 with this method.

I loved this game! Very unique concept, really had me on the edge of my seat in a panicked frenzy, fighting life and limb to survive and protect myself. I was around half my health, and there was a wave of those homing spike-balls that were centimeters away from my string, and I knew I was done for, and a torch powerup suddenly appeared, and as I struggled for it, the INSTANT before I touched it, the game was complete, and I had emerged victorious. I have enjoyed this game fully, and I also enjoyed your other game, Convey, and I look forward to playing other games by you and waiting for more games from you in the future. Keep it up, 'cause for 48 hours this is an amazing game.
