Thank you for playing and for your comments, the best part of the jam is having others play your game and give you their impressions
The idea was to have various types of black holes (at least an additional one that pushes you) and have the visuals represent better the area of effect of them, but I ran out of time.
I intend to improve the game after the jam and one of the ideas is to develop an editor tool to predict the trajectory, so that I have an easier time designing the levels. Maybe have this system work during gameplay too would be nice, at least for an "easy" level.
