I'm surprised it took this long for a leaderboard to pop up and I may join up later (at least, it is/was my intention to run this game, but other priorities came up), but I just noticed the GDQ submission so figured I'd take a look.

I figure you may have seen it already, but last year a run was done by Mountebank, which while solo, sits at 26:52. In case you haven't, you can find it here:

It may still be of assistance to you for the submissions, I'm not sure how much the levels differ between the solo and co-op run :)

Good luck at least!

Hi! We've seen this run before but it's definitely cool. The coop levels are completely different from the solo levels, literally none of them match up, not even the bosses! So it may take a little bit longer to get the time down. Thanks for the support though!
