Very good even if I'm not a yuri fan. The play loop is fun, I like how each different fairy has their own combat style so replaying the game three times for the ending wasn't boring. I also liked how the title screen updates, something that clued me in to making sure to complete each route. The art is cute and the fairies got very big, and do I detect a slight inspiration from the Legend of Zelda to the fairy design? All in all a project that I give high marks to.
If you decide to revisit the game in the future, I think it'd be fairly (heh) cool if the upgrades you pick were reflected on the MC during play, kind of like Risk of Rain 2, and maybe getting the ending unlocks a sort of endless mode where the mc is sporting her newest addition and her new GF replaces the maid upgrade.
