Wow, thanks for playing that far!
And congratulations on figuring out all five patterns!
You are absolutely right, objectives 13 & 15 are currently impossible to clear.
It's completely my fault too. I changed one of the pattern after setting up the objectives and I didn't check thoroughly enough to make sure everything still worked.
I plan to fix this issue (and a couple others) in the post-jam update.
Anyway, sorry about the inconvenience and thanks for the feedback!
Oh and I love your team's game, by the way!
Definitely one of the most memorable entries in this jam in my opinion
