I’ve read one where the guy basically had Minecraft powers and so he built a wall and then destroyed the supporting blocks and the wall stayed floating in air.
It had the potential to be pretty interesting, but it quickly turned into a monster girl harem manga.
Not that there’s anything wrong with that in and of itself, but I gave up on it when the lead heroine used sleep magic so that the average japanese man MC could be raped by a bunch of harpies.
There was also a disturbing amount of butt stuff forced on the MC. Kinda weird all in all.
The rape is off camera and downplayed immensely, but 8t does happen from an objective viewpoint
