There's a difference between being lazy and things taking longer to do as the quality of the game and the animations improves. Games like DIK, Become A Rockstar and Broken Dreamers takes time to deliver that quality. Not every VN can get out an update a month, some like Haley's Story can for the most part, even then the good devs give weekly or monthly updates, letting you know what's going on and keep you informed.
Then there are people like IC who simply get bored with a project, lose interest and then string people along and start other things instead with little updates. Case and point he comes back with a new game, talks all about it and then when it comes to Milfy, the game most people were supporting him for and want and update one, a game which according to him was 80% complete or something 6 months ago not a thing beyond Work will be a lot slower on it, whatever that means.
