The game doesn't really have an 'ending' as such no. It was intended to be a gameplay expression of being an immobile blob who can't do anything (including win the game) but maybe I missed the mark. Instead you should collect as many achievements as you'd like and then stop playing.
If you want to view the script you can find it in the data folder, in the Commands.json file. If I ever find the time I'll write a walk-through for people who want to find everything but are a bit stuck.
Thank you for that.
I do not mean an actual ending, per-se, but rather if the game is perhaps lying to you about the achievements in some parts, hence the quotations on the word "end." At least that is the impression I get, which is hard to blame when guidance seems rather sluggish even after some of the touch-ups the game got supposedly.
