Unfortunately, until now the average time for new updates was a bit long (~3/4 months depending on the new content, and I had a few delays too).
The custom features (gallery, shops, phone menu, etc.) that I added to the game took quite a lot of development time, but thankfully, they will be completed as of v0.05.
This means that after that, I will be able to focus almost exclusively on adding new content (characters, scenes, story, etc.), which also means faster updates!
