Awesome gameplay. The game could use some variety, maybe levels with increasing difficulty, but core gameplay is very funny. Graphics make me totally forgot it is 64x64, sound is somewhat annoying but well, match the style.
At first i've tried to destroy factories, and on high speed it wasn't evident that it's impossible. Sadly right now high speed is useless - I think some dangers on the field could force a player don't always fly at minimal speed.
