Solid Gold is a jump-and-run platform game created in 2013 for the Amiga by Frank Wille e Gerrit Wille (Night Own Design).
Inspired by classic platformers like Rick Dangerous and The Great Giana Sisters, the game features 10 levels and 4 worlds, each one with different graphics and enemies, but also nice sprites and great animations, thanks to the programming entirely in 68k assembler. There is no shooting: enemies must be eliminated by jumping on their heads. In fact, the joystick button is not used (but the second controller button can be configured for jumping).
One of the best examples of the Amiga pubic domain. Try it, and you won't regret it.
