I have found a few things to say…
1- There is a problem from CI3 till now… when a level finishes, your spacecraft will remain on left/right rotated position for a few seconds…, even if you dont move… see on this video:
2- The dropping keys are only rotating on their Z Axis; i think it will be better for them to rotate on other axis too… right now they seem a little abnormal.
3- When you’re on a electric mission, the weather of whole planet is Lightning; but they only affect on you! this is a little wrong, i think it is better to lightnings Affect enemies too, by decreasing powerful enemies’ health and kill weak ones (like chicks).
this will make game more realistic and won’t make it very easy too.
