In 1979 Atari Inc released Lunar Lander for the Arcade, and the object of the game was to pilot a lunar module onto the moon via a safe landing. Using vectored thrust you had to avoid obstacles such as the landscape while safely navigating to the required spot for a successful completion. I found it very enjoyable for its time and was pleased to learn that not only was there a Lander Challenge, organized by the Retro Programming Italia, but one of those games entered was a Lunar Lander like videogame for the Sinclair ZX Spectrum called Project: RE.VE.LA.TION.
In this new game developed in C language, built with z88dk, using the SP1 software sprite library and the BeepFX beeper sound effects, with levels designed designed with Tiled and converted using NTiled. Not only do you have to control a rocket's descent by changing its thrust and orientation while also trying to make a safe trajectory to the landing area, but you must also avoid crashing into obstacles and hitting the landing pad at too high a velocity.... So good luck!
