Thx Randil, I hope you'll be able to watch it soon. Some notes on the improvements: For all improvements it's noticable the actual amount of frames saved is close to a multiple of 16. Lolo spends 8 frames walking half of a square, and 16 frames walking a whole square (you should think about why an improvement in a level can never be a half square). Levels 1-2 and 1-3 are improved by a multiple of 16, so no further notes. Level 2-1 is improved by 62 frames, I lost 2 frames by manipulating the enemies movement, but saved 4 squares (4*16-2=62). In level 3-1 I am 2 squares faster, but lose a frame by having to shoot the snakey again (this second shot saves the 2 squares, so this is 2*16-1=31 frames faster). At 3-3 I used a strategy that involved shooting enemies, instead of freezing them, manipulating their movements costs 1 frame less this way. 4-2 and 6-5 are both a frame faster since I plan the shooting of the snakey's better. The route in 7-1 is 2 squares faster, but I lose a frame for having to shoot the enemy.
