Meh imo i kinda agree with op about it being more of a test etc BUT in a sense its rather more of a DDR game.
Ppl can still good by "reacting" to the "incoming" arrows and try their best to follow up without making " too many mistakes" that will eventually make them lose.
But ppl like me who don't have much practice pretty much will trip up on the 1st "set of patterns".
Whether its due to our slow reaction speed, nervousness or just plain no understand. Its just not for us.
I'm fine with that and will try again every now and then but hey its " not for everyone " just like how A LOT of ppl don't do sightseeing logs/ gave up or have 60+ TT cards.
