This is a FE7U hack with edits planned by Mekkah and made by me to challenge (as well as terrorize and enrage) Mangs. The final version was done in June 26th but there was a small text edit that I forgot back then, which I did for this upload. Hack made with FEBuilderGBA.
If you want to challenge it yourself, I recommend playing it blind like Mangs did. No screenshots or changelogs were made for that purpose. But if you’re more interested in watching him suffer instead, bellow are playlists with solutions and attempts.
