problem with exam task for college

[jeltedeproft at hotmail.com]

this is again a newer version, right now the velocity does in fact turn, but the view doesn't follow, it keeps the ship vertical.

i'm also having trouble letting the flame appear when pressing the "up" button

and when the ship rotates the horizontal velocity keeps getting bigger and bigger

i also have to make the game end when the ship hits the moon on the wrong place

i'm kinda stressed out because this has to be done by the 15th i've been studying like crazy the past week. If anyone could help me out i will deeply appreciate it, here is the code
