Improved the beginning a bit (about 30 position units). Needed to delay a frame to avoid enemy attack. Lost two frames due to unavoidable lag.
Can't efficiently jump over the last enemy after boosting of the other enemy (Branch 8). Branch 7 finishes the level, but 1 frame is lost. Branch 4 has the best position gain, but it it's to far away to hit the last enemy and to close to the enemy before the boxes.
