My favorite god in the book is Lord Randy, the god of power and combat. The abilities are amazingly flavorful and cool nods to iconic media like the Death Bringer's "It's Too Dangerous To Go Alone" ability or the "War Wizard's Devil's Crit" which allows you to max out spells if you roll three 6's on your dice pool. My favorite shout outs in the monsters were the Combat Amphibian and Drool-Aid Man.
I can spot some small parallels with 5e D&D, most obviously how warriors get an extra attack at 5th level and that spells go up to 9th level, but it doesn't distract from the game much. The system does heavily rely on random tables to resolve nat 20s and nat 1s which in my experience is very dangerous since there's a 5% chance each roll of having to roll on those tables which can be very deadly either to the PC or to their foe. I do however, really like that each class gets their own critical hit table that is flavored after their unique abilities, that's a nice touch. The classes only go up to level 10, which I actually prefer. I also really like that HP and gold costs tend towards lower numbers, a thing I wish more RPGs did. The rules reference sheet at the back is really smart and helpful.
My biggest complaints are visual things. The Burliness table on page 4 is organized strangely but I think that's just a formatting error. The maps on page 54 and 56 are also difficult to read for me and I imagine would be near impossible for someone who's red-green color blind (it'd also take a ton of ink to print on a typical home printer). When I brought both of these up to the publisher he said they'd look into the table and are planning on including a black and white map as well.
Overall, it's a solid, simple system that looks like it'd be pretty fun to run, especially for a one shot.
