Hello again,
So far I completed ending 1,2 and 3 (in two different ways) and did not use your or any other walkthrough. Eager to complete the other two.
First some English mode spelling corrections:
If not already done, you should revise the text at the character select a bit more. For instance, Alice's description text: oportunity has to be opportunity, bitten "on" should be bitten "in".
"Salty rat" has to be: "salty bat".
Agent L is called "Agente L" (still Spanish) in ending 3.
When in your inventory, look at blue cup gives the Spanish description.
However, use blue cup with water gives the correct English description you would expect when looking at.
Maybe it is intended, but shouldn't "the real midnight" just be "midnight"? (But then again, I haven't solved this part of the puzzle yet.)
And maybe you could use some text or effects for the hearing impaired, as two puzzles give essential audio clues. (Octopus room, ox head room.) Speaking about the "ox head room", that took me quite a while to figure out and it was actually by accident when I did. Therefore I suggest to use a different sound as you leave (what I refer to as) the "trigger" tile.
Lastly, is it possible to disable the debug keys? I am not familiar with Adventure Game Studio but perhaps you forgot?
