It's a good twist on Splatoon 3 gameplay, with enough variety in levels and upgrades to give it a decent amount of playtime. So far though, I sort of dislike how much it seems to lean on meta-progression between runs, giving it that feeling of "you can win without much skill just by persisting and dying enough times to make the game eventually hand you a victory". And given the quirks of Splatoon gameplay, namely that enemy attacks also can restrict your mobility, so a single mistake can cut off your escape and lead to a cascade of failure, it becomes very necessary to lower the difficulty as soon as you can.
Still, it feels worth the asking price, and injects a cool new mode into the game.
