Thank you for playing and your feedback! Thank you for pointing out failure chance. I've updated the page description to talk more about it as being related to training as opposed to the potential outcome of a match (although thats an interesting idea in and of itself!)
Noted about skip and retry. Feel kind of silly not adding retry in to begin with. Literally the whole point of games like these. As for skip, yeah lol. I wish I would've dedicated more time to solving that one. It acts more like a faster speed button than what you'd expect a button that says skip would do.
Once again thank you!
