Having multiple solutions makes it much easier to stumble into a solution, and the puzzle becomes less "tight" as a result. It's not always a bad thing, and with your style of making problem-solving levels (where you don't have a solution in mind) I'd say it's fine.
if this has a 74 then I'll come back to this, but there's like 2-3 ways to get 76 unfortunately
EDIT: It's not like MORALLY bad, but it feels a lot more clean when there's one specific thing a puzzle requires you to do and everything else falls short.
