Man, not gonna lie.... this update is kinda disappointing... the new content with the mom is almost none, and the option to do the scenes on the Onsen just disappeared; the scenes with the sis are nice, but stops really abruptly.
For about 04 months of work, even if the creator does this part-time or a couple of hours a week, that's not a great amount to a "big version update", more like 02.5; I don't know if he/she felt pressured to release something "so soon" by the community/patreons or if he thinks is a good amount of content.
For a changelog of " 932 renders 87 animations" as someone posted, this is a 20min max gameplay with no great feeling of improvement; maybe is because of how he renders this stuff or about the "many variations of the same scenes" aka other angles, but it doesn't feel at all that we have all that new stuff.
I know that I don't have any rights to criticize the game, as I didn't support the creator, but it seems to me that we will have a heck of a long time and slow pace to get somewhere; maybe 2 years from now with 4 or 5 new versions released we will have actually hot stuff to see it, if it doesn't get canceled.
