the main problem is that the projectile can continue flying outside of the visible area and sometimes get stuck there without ending the level. some option to abort the level without restarting would be nice.

or a way to zoom out so that one can try a trajectory that circles around the planets instead of through them. some levels can't be solved because i can't move the mouse outside of the playing area in order to get the trajectory that's needed.

i'd also like an option to replay a specific level. since levels are randomly generated i'd like to be able to replay a level until i can solve it, even if that breaks my streak.
