I squeezed even bit further. That's the first one I'm really proud of!

Level 24, and yes ! Its really elegant.

My level 17... Wonder how to make it cleaner, but algorythm is simple: mark begining with one yellow dot, another yellow dot moves one step each time, then a green one, that moves 2 steps each round. When green meets yellow, eat both and terminate.

Afterwards one can think a bit more and make your favourite solution even prettier (check the programms of three leftmost controllers :) ). Isn't it agreeable?

Programming requires continuous thinking and rethinking your design. Going for the first solution that comes to your mind isn't bad, but certainly while programming it you should constantly revise and simplify. If you do it right, your Brimstone solution should look more or less like this.

Since there is to little time to react its just random wheter you can avoid next incoming plane or not. You could post dice throwing contest with much less effort. 2/5 just for the efort done. Could have been much better. And funny thing - getting hit while going upwards leads a plane to dead stop while still in the air. Is it a bug or a feature?
I thought that peace tank - half off, suggested that i shouldn't shoot for 15 seconds, and then destroy the ufo. Quite misleading. Other than that, pretty easy. And yeah... the posters help a lot.
