There might be an excuse for an off-year, but the issue is that the updates have been lacking in content and with huge gaps since it first released and this is what makes it a "confirmed leech" for me. I can still recall being hyped for this game, and every update it got, it added a new character introduction and small amount of content for them, instead of working on the "main characters" who you're most interested in. Then suddenly the dev went for reworks instead of new content - UI, UX, pointless minigames, etc. The content when it first released and 3.4 - the "landlady" and "sister" content didn't really get anything new (maybe 1-2 scenes in 2 years) - which is why I think the dev is just following in the steps of Waifu Academy, Dual Family, etc.
