Thanks a lot for the feedback!
I'm glad you made it first try! I think the balancing has this problem whereby more hardcore gamers who are really familiar with mouse aiming and timing (fps, rhythm games, mobas) find it easy to beat, whereas many have found it too hard, especially getting through the first nights. It's an interesting problem to have a very wide range of people saying too easy too hard, but ultimately it's up to us as game devs to make that gap a lot smaller in ways that don't take away any fun or depth.
I'll be taking these thoughts into any future updates / more game jams I participate in, thanks again!
