Feels good to play and has nice variety in its levels. Took me about 4 tries to 1CC after credit feeding through the game once. I loved the soccer stage (it's just like the world cup, but in hell) and I didn't love the yuri forest but I still think it adds something to the game in terms of variety even though it's either scary or a slog depending on how carefully you clear out enemies. The game is pretty much perfect for what it is.
Also, the music is absolutely amazing. The stage 2 theme in particular is incredible. "GAY LASER FROM HELL" is something I'll never forget.
