If you're looking for a challenge (think Sekiro, Dark Souls, Elden Ring in terms of difficulty, not game play) this is your game. There's only 5 levels and I've admittedly spent days on certain levels because the game challenges you.
If you're the type of person who likes to spam buttons to advance a game and hates to lose over and over again, this game isn't for you. To me, there's something satisfying after dying repeatedly and finally winning.
