I gave it a play and I was kind of disappointed with the balance. It seemed like the monsters scaled with the player, which is fine but they were very powerful. Maybe it was the character I ended up getting from the initial choice sequence (which was very cool by the way) but my guy seemed to have very little defense and negligible attack stats, even after purchasing the best possible gear.
Also, the encounter rate was WAY too high. For a puzzle based dungeon, I really don't like taking two steps and encountering a monster.
I will say, the attention to detail with the Egyptian mythos was spot on, and the mapping and art were both excellent. Sound fit well and helped with the atmosphere.
Most of the puzzles in the dungeon were fine, although I encountered one in The Temple of Isis that was basically just guessing which switches to pull and while a trial and error method wouldn't be a problem in itself, the aforementioned encounter rate really made that floor of the Isis dungeon feel like a chore.
My suggestion is to alter the encounter rate and work on balancing the fights a little bit more. Also, perhaps after each dungeon is cleared, perhaps offer a story moment, even if it is small so the game doesn't feel just like a crawler.
