Don't listen to the hype, this isn't worth your time. It's a railroaded dungeon with high-lethality traps that have no warnings and "lessons" which either don't come up or aren't clearly written. Skerples has been asked about why the encounters fail to communicate lessons and dodged by saying that not ever lesson in his training-wheel railroad dungeon needs to be learned. But if there every lesson doesn't need to be learned why are you playing/running a teaching dungeon instead of a regular dungeon? What Tomb of The Serpent Kings does teach is to play in that particular flavor of False OSR full of "gotcha!" death traps and "deep" but pointless fluff.

Could it be fixed? Yes, but so could N1 and Castle Spulzeer. By the time you're done "fixing" TOTSK you might as well have written a new module

I did a more in-depth review on my blog but here's the condensed version: Apes Victorious does exactly what it sets out to do, which is to create an OSR Planet of The Apes rpg. However it doesn't go beyond that goal to do anything interesting in either a mechanical or narrative sense. The final product isn't bad by any measure but on the other hand it isn't great either. It's just there.
