The point of the upgrade wasn't really to collect the coins fast, but to be able to get them even if your speed is a little high. Thanks for the feedback though, I will take it into consideration. Thanks for playing!
Game is broken after latest update. Won't progress, just stick without killing anyone. If I prestige, and reset heroes, start on lvl 1 without animations or nothing, just paused.
1.- The fingerprint one was illogical. Is impossible to connect the ancient scroll to the image with the UV light as there's any clue that shows any connection between them, and the ancient scroll do not show in any way that you have to count. Coming from a bunch of puzzles with symbols, the ancient scroll seems a symbol for a future puzzle. 2.- The "UNLOCK" thingy is really illogical. Any clue to tell you that you have to draw each letter anywhere. 3.- The 2823 thingy, also zero clues telling you that you have to use the old phone keyboard method. 2/5 because a puzzle game with flaws is so frustrating without reason.
