Thanks for the feedback!
Now that you mention it, I didn't plan the control scheme too much because of being busy with other things and only used arrows to move when testing, so Z made sense to me at the moment.
And yeah, you're right, some moments are easy because of how patterns work. I thought at the end that making the patterns rotate uniformally instead of following the player around would've been better but, as always happens in Jams, time's short.
I'm glad you enjoyed our little game in spite of those issues! :D
