I don't know whether I "finished" it in 2014, I had explored more before, but only now did I get the screen in the attached image in . It didn't run on my previous computer, so I couldn't play it there, unfortunately my old laptop died and I'm back to this relic of a desktop computer, which, despite having a worse GPU than my dead laptop, happens to run Guacamelee! and [url=http://www.gog.com/game/stick_it_to_the_man]Stick It To The Man
So, instead of exploring and trying to collect everything, I went straight for the ending and finished the game. Now, all there's left to do is get all the orbs, collectibles and the El Inferno unlockable costumes I'm still missing.
Here you go, A WINNER IS YOU!:
[EDIT] I absolutely loved this game. The humor is awesome, if a bit too much on the memes and game references, for some people (personally, I enjoyed it a lot). The platforming parts can be a bit hard, especially if you're going for each and every collectible, and some boss fights can be a pain in the butt if you don't apply everything you learned until then (never forget to roll, the devs said one of the game's flaws is they didn't stress how important it is to roll/dodge, and when I started using it more often, hard fights and some more obnoxious platforming sections became a hell of a lot easier), but I played through it all using just a keyboard and it's perfectly doable. Try it if you like a good mix of 2D metroidvania platformers with a nice touch of fighting/brawler game thrown in.
