Gold is used to make the player's armor and shovel better, buy more health or magic, or buy Relics (useful items that use magic). At the end of the main levels, the player will have to fight a boss, usually an enemy knight, to complete the level. The player can destroy checkpoints to get more Gold, but in turn, the player will have to start at an earlier part of the level if they die. Like in Dark Souls, the player will have one life to take back the Gold they lost, but if they die before taking back their lost Gold, the lost Gold will disappear forever. There is no game over if the player dies in a level, but they will return to the last checkpoint they turned on and lose about one-fourth of all the Gold they have, the game's currency. The player will use the shovel for fighting enemies, jumping on platforms, and digging up treasure and secrets. The play plays as Shovel Knight, a knight who carries a shovel rather than a normal weapon like a sword or a spear. The first campaign was later renamed Shovel of Hope. These all were sold together as Shovel Knight: Treasure Trove. The game later added four more campaigns, or separate stories and/or game modes within the game, which are Plague of Shadows, Specter of Torment, King of Cards, and Shovel Knight: Showdown. Shovel Knight's success on Nintendo's consoles them more popular to make indie games for. Before Shovel Knight, Nintendo mostly released first-party and mainstream video games on its own consoles, but since the Wii U was struggling to sell, it allowed Nintendo to be more open to playing indie games on their own consoles. The game is even responsible for expanding the indie game market for Nintendo consoles. The game has received many good reviews, has won many awards, and often shows up on best video games of all time lists. The game's gameplay and looks are based on other 2D platformers from the Nintendo Entertainment System (NES). It later came out on PlayStation 3, PlayStation 4, PlayStation Vita, Xbox One, Nintendo Switch, OS X, and Linux. It first came out on the Wii U, Nintendo 3DS, and Microsoft Windows. The money needed to make the game came from Kickstarter. Shovel Knight is an indie 2D platform game made by Yacht Club Games in 2014.
