Momodora: Reverie Under the Moonlight received an 82/100 aggregate review score on Metacritic, indicating "generally favorable reviews".^[11] Chris Shive from Hardcore Gamer gave the game a 4 out of 5 score saying, "Momodora: Reverie Under the Moonlight is the ideal mix of old and new. The visuals and 2D platforming scream '80s NES, but the detail that went into the pixel art and the attack combos mixed with fluid animation give this title just enough of a modern feel so it doesn’t feel dated."^[22] Destructoid's Nick Valdez rated the game 8 out of 10, praising its "tight, intense combat," but commented that the game's soundtrack was "unmemorable, and not functional at all times."^[23]
