There is a new patch file although you can still play with the old one. The only thing missing in the old patch file is in the scenes where you see the girls naked sprites they will have “beams of light” covering their breasts as they are in the “all-ages” Steam release. Downloading the new patch will get you updated and “uncensored” boobs too.
In a review I read when Mofu Mofu Edition first came out a feature that was requested was to have a text box that appears behind the dialogue that you can dynamically adjust the opacity of! Hopefully this makes the scenes where there is white text on over white easier to read and doesn’t get in the way of the character sprites.
