Lunar Rescue is a remake of the 1979 Taito game. You can download all 71 of the Crozza Remakes here.
Like many of his remakes, the game is accurate but has different graphics and colors. You release your ship from the mothership and try to land and save the stranded astronauts. There are three landing pads and six astronauts to save. You need to avoid spaceships and asteroids.
We don't recall this game, it might have been just before our time, but it reminds us a little of Lunar Lander, a game that was released the same year. We found it challenging and think most could discover Lunar Rescue to be a fun time waster.
F4 will switch from full screen to windowed mode. Space will release you from the mothership and shoot upwards at enemies. Left and right arrow keys to maneuver, and down arrow for thrust. Like all Crozza Games, the game is portable, so no installation is needed.
