Goblin and Coins II (I'm the author of this game) is a difficult 2D pixel-art platformer with a unique twist - after the player loses all lives and all continues, they end up in a challenging level called the Underworld, where they must assembly the Golden branch in order to resurrect with additional continues/lives.

Of course, the game can be made easier (or not - create your own challenge!) in many ways, including purchasing up to five upgrades in exchange for the collected coins (additional life, double jump (recommended first purchase), 99 continues, instant shrinking to gain access to crawl space tunnels, and seeing the invisible objects/levels) and using an "easier start" gameplay option in the settings menu (on by default).
