Decent game. I wouldn't really call it a metroidvania. It feels like one, but its entirely linear. The only backtracking is for optional stat upgrades that feel pretty lackluster. The game play is good, but isnt really anything special. Especially when optimal strategy devolves into spamming thousand knives. Good level of challenge. The best part about this game is how short it is. Much longer and it would overstay its welcome.
