I like the potential here. Right now it’s a bit tedious to edit, but the level of control is also a good thing.
I think if you were able to introduce a few features that allow for bulk editing (like messing around with group parameters, and selecting multiple vertices at once), then you’d have the best of both worlds: fine level control + fast editing.
Overall, I really like what you’ve got going here. There’s a lot of work that’s gone into this, especially for a jam, that’s plain to see.
Excellent job! Good luck if you continue with this, I can see it being pretty useful for people.
