Yeah, you only have 2 options now.
Start a new game or mail Alec, or just hope he will see this topic. I'd send a mail either way, with a link to this topic too.
Seeing the 3 boys are down there and the boy is crying in the end boss room AND the body is still closed, you can't really progress there.
I must say however, playing Aquaria twice in a short time is easier for sure, so starting a new game shouldn't be.. THAT much of a trouble, if you enjoyed it. Seeing I have NO clue when Alec would respond to this.
Either way, you should post your savegame on here. It's in the Aquaria game folder and then to the folder save. (c:/Program Files/Aquaria/save or something.)
If you have multiple save games in the folder, you should know that the
files start counting with
zero and the
save games in the game start counting with
one. So you should add 1 to the files to find the right one.
Then archive (zip or rar) the two files, one being the screen file and the other being the save file. And host it on
WillHostForFood or something.
I hope you understand what I just said and that you will succeed, I would love to look at this, and as so Alec can already access your save file, if needed.
