A huge waste of time. I saw another review on here say this game is 90% gameplay, 10% porn, well I'd say it's 99% gameplay, 1% porn. This is the slowest burn porn game you'll likely ever play, giving you a granny rape scene (who doesn't love those, am I right!?) then virtually nothing but teases and groping and dating ... when the game's kind enough to even offer those.
Gameplay wise it's much less fun than your typical porn game. Typically the gameplay frame work has you getting money, building stats, and building your affection (some games do this part much better than others) to advance a route; in Innocent Witches that's all there but it's thrown at you at your desk and it feels extra grindy and mundane. You basically sit at a desk and call girls or faculty to advance the plot, and boy oh boy is there a lot of plot and task work related to it.
I'd forgive this mundane, grindy, non-interactive gameplay if it led to much, but it really doesn't lead to much at all. As of this review, May of 2021, IIRC there are two granny sex scenes, one BJ and one regular sex scene, then a WHOLE lot of groping and spying. Discounting the two granny sex scenes that's a grand spanking total of two good scenes, which is a fucking shame since the art's so beautiful and the two good scenes are actually quite excellent! But I'd never recommend you play through the game to get to those. Check them out online.
This game leans on its beautiful art so hard. The gameplay, lack of scenes, and even the story are all not my cup of tea and I imagine the typical fan of Summertime Saga and the like will agree with me, there's a large lack of fun.
Maybe in a few years if there are actual scenes I'll give it an updated review.
