I think I wrote something about that in the tutorial, it's either you missed it or it isn't clear enough (The circle beats always appear after a beat that only goes up like this )
Thanks for the feedback! Might be something to consider when I decide to add more stuff to this game!
Thanks! The last stage is a bit glitched, sometimes the player/the boxes duplicate themselves, I feel like it is not possible (I didn't find those bugs before submitting so...), but thanks for the feedback!
