Iron Meat is a 2D run-and-shoot type of retro indie game with a high tribute to Contra, developed by Ivan Valeryevich Suvorov from Russia, using Unity. It comes with an onslaught of mechanics ripped from arcade and console classics - mainly the classic video game Contra, but contains graphic pixelated violence and gore throughout.

Silver Night's Crusaders is a fan-made, Castlevania-based free game for PC and Android platforms, developed by True Role Dreams (Crimsondeath) from Spain using OpenBOR game engine. It isn't a metroidvania, instead it's more of a side-scrolling arcade action game, which splits into several stages rather than a massive sprawling map.

Toziuha Night is a metroidvania-like, pixel-style independent 2D action adventure game series, developed by an amateur game developer Danny Garay from Nicaragua, using Godot game engine. Danny Garay is a big fan of the Castlevania series, which shows how much his games have been influenced by Castlevania works.

Exanima is a dungeon exploration based hardcore action role-playing game, developed by Bare Mettle Entertainment from London. Players need to explore, fight and survive in a dark underworld (set in the Middle Ages of Europe), collect weapons and items, defeat enemies, solve puzzles, and finally find a way out of here. The overall game is very demanding on the player's controls and tactics, and clicking a mouse like in a traditional A-RPG won't get you very far.

In the early 1990s, 2D arcade racer video games had great success on both arcade consoles and 16-bit home consoles, delivering a stunning integrated gaming experience. Until the mid to late '90s, it was surpassed by the full 3D GT Racing, Ridge Racer, Need for Speed, and so forth series. Nowadays, the graphics of racing games have evolved to resemble the real world, but the obvious side effect of the excessive pursuit of realism is that the game controls become more complex, thus losing the fun of the game itself. As a result, many gamers miss the simple, exciting, relaxing racing experience when they could easily compete with friends.
