Well, after watching Button Pushin's video from time to time when I got stuck, your comment on his YouTube video, and dying several times to the last boss, I managed to beat the game.
I'm not sure what other items I have to collect aside from the apple and all the hearts in the normal game, and I couldn't figure out what to do after searching most of the rooms in Neith Mode.
While I was stuck at first after using up all of my clones, exploring the game's many rooms helped me to get my bearings, so I enjoyed playing through the game. As such, I would like some advice on how to proceed in Neith Mode, seeing as there's only so far I can get by as Neith before being perplexed as to what to do next D:
Hi, hello. Thank you for sticking around with the game for so long!
If you right-click in Neith Mode she can teleport around, perhaps you noticed some Egyptian-themed items Merope could not pick up in her journey. Perhaps you could try to use Neith's powers to get these items and then retrace Merope's steps when she left the castle ; )
Hi there, I explored the whole game again by keeping an eye out for said artifacts, managed to first get the normal second ending, collected the remaining sword bits, and then got the second version of the true ending. The only thing left to do is to collect all the remaining items, which I must have missed out on while playing the Merope mode itself :p
