i mean if you can port it to godot then go for it. the writing and art are really fukin good, i personally dont even mind the lackluster gameplay, for visual novel standards this is pretty normal tbh. i personally have no idea how i'd change the gameplay without making it annoying for the player to deal with. so keep that in mind, the draw of the game is its character's story and art, try to have the game mechanics enhance that rather than be its own separate thing. i have faith in u!
