Unfortunately not at the moment. The frame is fixed, I would have to rewrite the entire game and customize everything. I might do an RPG Maker MZ port at some point in the future and look at Zoom options for Android there. But at the moment my new titles have priority. I'm very sorry. I've been really short of time for a few years now and I just hope that things will get better in the next few years so that I can start working on something like this too.
Oh don't worry about it ^^ I just looked at the long list of your creations, you are very busy and working hard. I am okay playing with the frame. It seemed like a trivial change to my smooth little brain xD not worth rethinking the whole game over. I too hope things get better in your world.
I've been playing this on & off for about 3 years now, I can't stop coming back to take care of little neko :3
I'm glad to hear that ^^. Sometimes the simplest changes involve a lot of work. When I remove the frame, I'm left with a 1-tile black border on each side. To make it truly borderless, I would have to move everything in the game and readjust every event and image. I think this could also be solved with a zoom, but depending on the Android device, this could lead to complications and simply look stupid with pixel art rendering. But I've often thought about reworking and porting the game. But rather when my other projects are finished.
