As something funny, it's a fun novelty.
As an actual game, the difficulty is too high. Plus, I don't know what conditions to get for each ending.

the 4 endings are based on 2 factors: water quantity and cleanliness:
- low cleanliness + low quantity -> bad ending that seems bugged (the dialogue cuts off in a weird place)
- low cleanliness + high quantity -> very bad ending
- high cleanliness + low quantity -> pretty good ending
- high cleanliness + high quantity -> bath ending
