Action 52 (NES)

The game was developed in 3 months by 4 programmers (who hadn't developed NES games before). That means that each person had to finish writing more than 1 minigame per week.

02 STAR EVIL is a scrolling shooter where the only challenge seems to be avoiding a block right in front of your ship in the beginning of each level. I reached level 2.

08 JUPITER SCOPE is a very boring and easy game where you shoot meteors that rain down on a city. I'm convinced the programmer wanted to make them destroy the city, but he couln't get it to work in the 4-5 days he had to finish the game.

42 BEEPS AND BLIPS: A multidirectional shooter where you can move in 8 directions, but only shoot in 4 directions. It feels OK in the beginning, but later on the enemies chase you as fast as you can move, and since it's impossible to shoot back, it becomes impossible to kill them. Also, this game has the issue where you can hold down autofire, and no enemies will spawn.

38 THEY CAME...: Another multidirectional shooter, another game where you can hold down autofire to prevent any new enemies from spawning. It won't help you however, since proceeding to the next level requires killing a certain number of enemies. It does get frustrating, because the enemies have a tendency to spawn and just leave the screen without you having a chance to kill them. I reached level 4 before I stopped playing.
