Thank you so much for playing!
I was afraid that the "loop" (or "cycle" as you say) mechanics were not intelligible enough, but it seems you've got it right, through and through. The music I have used is called "Magical transition" (which fits quite well) and comes from freepd.com.
BTW, it IS possible to reach 20 on the first loop (I've tried), which seems to indicate that some more balancing is due, or maybe just to step up the goal from 20 to 25 or 30. I cannot set it up too much though, since there is an anti-farming system at work in the background, and I'm afraid 50 is not reachable. I'll let future me do the math.
Thanks for your support.
