The art is pretty good, the menu is cool and the music is not bad (i would suggest making it loop instead of fade and then start again :) ), but i found a couple of issues.
First of all the game is not pixel perfect, so technically it is not 64x64 (that is only in gameplay since the game is 1:1 and the art does match, but just to point it out). It is a bit tricky to achieve this on unity, next time, if you can't figure it out, ask through the discord and there will be many people there to help you achieve it properly :). Then, the main scene at the beggining is pretty funny, i do get the reference since i'm a spaniard myself :}), but i would have written it so it doesn't finish in the next vignette since it was a bit confusing at first. Finally, the hitboxes are too big, sometimes i saw a square in the wall that i couldn't even enter, or be hit by a fire i wasn't touching clearly, but all of this is fixable :))
Now the good things. It has quite a good controller, i feel nice playing, in control. The AI seems good, works like a charm (but it feels weird to have so many life). The level design appears to be quite correct except in those squares i couldn't pass through, so that's nice, and you made looots of content, and thats quite good for a gamejam, congratulations mate :))))))
