@csk this is a really cool idea, but the finickiness of the interaction is kinda making it harder than it needs to be. might i suggest allowing the line to go backwards and being more lenient with going off the line?

ps nice 🎩

@Zimodo Thanks for the feedback.

Forbidding backwards motion was a deliberate design decision. It makes things a bit more challenging, and also prevents possibly paradoxical cases where you reverse the stacking order at crossings.

Leniency is obviously a more continuous question of tuning, for which there is no perfect answer. But it's definitely tuned to be pretty tough, because I want dexterity to be a core part of the puzzle.
