You are supposed to beat the game without continues (one credit clear).
Continues are for practice.
2hu 10, 11 and 12 have infinite continues but you restart the stage every time. This system was dumb and gay and I'm glad ZUN ditched it.
2hu15 Point Device mode has checkpoints but it's a meme game with ballbusting spells designed around having checkpoints.
Photogames are a collection of standalone bite-sized stages so long-term resource management and planning are irrelevant there.
But the standard 2hu gaming experience is beating the main story on one credit a feeling like a GOD as you're watching good ending's silly slide show.
