Thanks for the great feedback from me too!
Level 22 and the progression bug should already be fixed but we can’t upload it during the jam of course. We‘re also working on some additional levels to smooth out the pacing as well as a couple QoL improvements, so I hope you‘ll give our post-Jam version a try. ;)
Btw.: I think you‘re the first person to make it to Level 22 so congrats on being such a great puzzle solver! :D
