Yes, the Trash Hero Act 1 (The classic version) is already finished. We are doing all following acts in the next game with a better story format.
We may update Trash Hero 1 a few times though, to add images or for bug fixes.
Oh man I am always down for a new image or two on older entrees. I dunno where we will be in like, a decade but if this became a trilogy an all in on would also be neat. Anyway I guess I should get started for now, I am currently working up the courage to waste several hours trying to find the end for act 1. I have a feeling I may end up playing all night! It happened several times with My Very Own Lith.
