Guacamelee is a game that is far more than the sum of it's parts. While doing nothing technically new, this story about a Mexican wrestler fighting evil skeletons still manages to seem vibrant and fresh. How?
Bright colours and chickens mostly.
Stop me if you've heard this one before. Guacamelee takes place in an open world where all the interesting paths are conveniently blocked off by colourful rocks, large gaps and temporarily impassable architecture. The abilities to bypass them (a variety of colourful wrestling moves such as headbutts and uppercuts) are conveniently held under lock and key by difficult enemies at the far corners of the map. Yes, Guacamelee is a metroidvania game - complete with heart/energy containers, quick-travel systems and subquests. If you've played any Metroidvania-style games before, you'll most likely know the steps off by heart.
So what makes Guacamelee good? In one word, humour. Much like Jazzpunk (which I will bore your ears off about very soon...) Guacamelee is a silly silly game, and is proud of it. Random goat men try and sleep with your mother. There is a poster for Link as a mexican wrester (El Linko!) and one of the rock formations in the game looks suspiciously like Megaman. You can wear a full chicken costume, one of the moves is called 'DerpDerp' because they couldn't be bothered to give it a proper name, and one of the characters can turn into a walking egg at will.
So it's a silly game, and wonderfully so. The game is chock-full of references to pop culture - almost every poster is a nod to games characters, internet slang or just, y'know, random weirdness! Half the fun of the game is looking into every nook and cranny to find some new strange mexicanified reference, or some other throwaway joke hiding in the background. None of it is necessary to the plot - you can blast through the whole thing without stopping to appreciate a Minecraft-themed bar called The Neather Realm - but it's there to make you smile if you want it.
It doesn't hurt that Guacamelee is GORGEOUS. As mentioned, the game is garishly colourful - the whole thing seems to have been drawn in bright yellows, pinks and blues. And yet the colours are so vivid - and the animation so crisp - that it just makes the whole world come alive. The way your character runs, the way a chicken squarks when you hit it, the way the world seamlessly shifts between the worlds of Living and Dead... it's utterly wonderful, and even the act of running through the world is a joy to behold.
Lastly, I can't forget the music. As you would expect, the whole soundtrack is full of bouncy mexican-style tunes. Upbeat guitar and brass are the order of the day, and the melodies are as bright as the landscape you're bouncing around. It's the icing on a very pretty, very silly, very fun cake. Don't play it expecting to be wowed by any dramatic story or world-changing gameplay. Instead dive in and enjoy the humour, the music and, most of all, the colours.
Also at one point the Devil, disguised as a chicken, complains to you about Adele. That's pretty important right there.
