Hell of Interpolations

Let’s say I want to recreate that game (visual novel), it has amazing effect right? But after seeing those I’m afraid of how to do it on Java (Libgdx), there are so much tweens. Is hardcode every single moving piece one by one the only choice?

I see a lot of different dissolves and framebuffer effects, but none of them look extremely hard technically. The scene2d library in gdx might help with a few of them like the text fading, but the overlay stuff looks like hand-drawn layers that are panned over independently for each. Looks more like a job for Final Cut Pro or Adobe After Effects than a low-level graphics library, tell you the truth.
