That's an interesting way of completing the levels! I guess it's a side-effect of only needing a set amount of sequences to complete the level, there's not meant to be any discarded outputs. The point of the buffer is to combine two connections into one, so you can connect up different things to one action (I guess it was a bad naming choice, I copied the object from a buffer action I didn't use but never got around to changing the text). Here's how I use it in the first level with a buffer https://streamable.com/00n2jd . I'd love to see some of your solutions to the levels! I'm going to be posting updates in the discord server linked in the games description so I'd be grateful for your input during development
