I don't know what I was expecting, given I only played Niwa for the song, but it was very lackluster and frustrating. First off, the optimization or lack thereof is terrible. There's no excuse for it to run as poorly as it does post 2.2 game optimizations. It'd be a little more forgivable if Niwa looked good, but it simply doesn't. It's a derivative of a derivative and somehow looks worse than the ripoff level it was supposed to "rework". The deco progressively gets worse the farther you get into the level and isn't all that great to begin with at the start. The creator of this level only knows how to milk Wasureta, seeing as a third level in the ripoff series is being created, and set to be top 50 in difficulty. It's completely tiring to see all of this derivative reta slop, but thats a tangent for another time. Niwa is completely boring to play from zero, with much of that owed to the massive difficulty spike that is the ending. It's horrendous to play and makes the level like gambling when you play from zero. I wouldn't recommend anybody play this, as your time is better spent elsewhere.
