@Evernewb : I disagree with you, Astro fighter Ship is a better starting dogfighter because of his small size & incredible maneuverability, even if it is a lower-armored ship. However, that's true centaur is a really great ship, actually it's the one I am using now.
Snuwers, alien and human ships have the same characteristics, except human ships are generally smaller (so they avoid better unguided weapons), and aliens weapons are generally more powerful. You should have a look here : http://www.jestertrek.com/starfighter/
@anuragdbl : (level 22) You have to pull up the cannon, and use the teleporter to send the ball in the blocks, and the air of your electric fan will push the steam in steam detector.
@sora2421 : (level 30) you build two systems battery-fan-steam detector, in order to make music for your hamster : then on the right line you have put a puller in front of a battery, an electric fan and the cannon in front of the bottom electric fan.
Does anyone know how to complete the level 32 ?
Sorry for my poor english.
