This is a simple 2D shooter game that I started to make for my son. When he was around 5 years old, he started showing interest to my XBox, and wanted to try it anyway. I bought a couple of simple games including shooting ones (galaxy and space invaders remakes), but they were not good enough for us. They had either poor quality or too steep progression curve that after the 4-5th level it bacame so difficult that he couldn't enjoy.
Being a game developer, I thought it shouldn't be a big task to make a game that he likes, and also he can get some insight of how these things are being made.

As I never use any game making tool or commercial engine, I created a 2D game framework, so we could progress very rapidly. The framework is based on animated sprites with very fast pixel-precise collision detection. Making a game with thousands of enemies and bullets on screen is not an issue.

The game features 40 different enemies, 5 bosses, 32 missions and 11 different backround locations. The game is packed with wide range of weapons including 4 super weapons.
The total game time is around two hours for a skilled player.
