I am well-versed in the arena of high-speed action and gameplay, both rythmatically and in general, due to my liking for games such as F-Zero, Beat Saber, Synth Riders, and others. While this isn't a rhythm game, I use these as examples since I believe they help me understand when something is far too slow for me to tolerate.
If a game isn't challenging my physical response limits, I don't find it all that quick or exciting, especially when all it's doing is punishing me for being too fast. Perhaps due to personal bias, but the game itself is really clunky and buggy in a variety of ways. My 6-hour gameplay seemed unsatisfying and monotonous from start to finish.
