What i mean is you should make the snakes meve forward and have a smaller chance of turning then they bounce away from walls. My game eat the pie2(http://www.greenfoot.org/scenarios/5208) has enemies adn they move around alot rather then slowly move

you should make it so that the asteriods keep spawning by putting a similar generation code into the act method and you should make the initail asteroids only spawn farther forward than you ships location so you can't spawn in an instant death trap. One last thing when the asteroid kills you should put Greenfoot.stop() on the next line so it stops. Cool secopnd game though. I'm playing your first now.

With the ice once you try to stop in the direction you are moving, you slide a about the length of a block. Have you not noticed? Try on the first ice level, go forward on the ice and then stop before the edge and you should fall off. I think i know how to fix the second problem but it will require alot of new code that test if you are touching the block and then code to push you. I will probably fix it in the next update.
