I just finished Guacamelee! Super Turbo Championship Edition.
I had started the game some months ago and dropped it cause I thought it was boring. Hell, was I wrong. Finally I decided to go back to this game some days ago with the intent to get it done with some backlog games.
Long story short: this game is amazing. The more you progress through the game, gain new skills and powerups, the more you get sucked into it and its greatness truly reveals itself. What I thought it was an average game turned out to be an amazing one.
If you haven't played it, I say definitely check it out!
