Wholesome, but not in a way that makes you roll your eyes. I'm normally not huge on vanilla games (though, tbf, this game might not be vanilla as I've not actually reached any lewd scenes that aren't in the MC's imagination....), but the art style and humor make this a really fun, laid-back experience.
The characters are all great, familiar enough to fit into typical archetypes, but individual enough that you actually want to learn more about them/follow their paths.
The writing is stellar. Really, really fantastic. TimeWizard, whoever you are, you are one funny MF-er! The constant stream of jokes land really well, and the dialogue choices are self-deprecating enough to not hate the MC, but intelligent enough to still respect him. 10/10, for sure.
The only reason I dropped a star is because of how intricate all of the quests are. If it weren't for the 'Guide' option, I would never have been able to advance past the first day of this game.
Just as an example, there's a moment where you have to find the school nurse. So you follow a collection of candy wrappers that lead you to a locked cabinet. To pick the lock, you have to go back to the nurses office and click a cup full of lollipops to get an unseen safety pin at the bottom of the cup. Then you have to collect a ball of yarn from a desk in your homeroom. Then you have to combine the safety pin and the yarn to make.... a safety pin with string attached, and for some reason THAT enables you to pick the lock on the cupboard. After all that, the nurse isn't in the cupboard, a cat is, so you have to chase the cat around, let it sniff the candy wrappers, then follow it outside the school to finally find the nurse.
(Keep in mind you will have a dozen or so quests like this going at once, at any given point in the game).
Like.... seriously?? There is nothing remotely intuitive about any of that. So the game is designed in a way where you HAVE to use the Guide/Hints, which inevitably makes it feel less like a game and more like you're just checking items off of a list. Which, in a VN with writing this good, is a real bummer.
Still, I would recommend this game to anyone. The quality of the narrative is well beyond 90% of most of what you'll find on these forums, and that deserves recognition. The art is great, the dialogue is great, and the plot is strong.
