When is box2d and similar overkill? Let’s say that I should create a game like geomertry dash(for those who know it) and 2d scrolling games in general, is box2d overkill since you in fact usually only need gravity and collision detection? I mean, when should I prefer using the built-in physics over box2d? Is games like flappy bird not even worth using the built-in physics, which actually seems very simple to use, and should I then simply do the collision detection etc. manually?
Again, as for all my questions, I would love to hear your thoughts, thanks!
