8A very nice and rather challenging old-fashioned game. Also great idea of releasing the sources, which one can be inspired by to learn how to program with Allegro.

4A lot of the improvements needed are just fine-tweaking. Some planes are flying backwards, the explosions are a bit much, it's very hard, and the controls feel unresponsive. Really cool level design though!

9I like old school graphics and sounds. The idea of the game is simple - control the plane and shoot your enemies. Easy steering, great fun. The only weird thing is that you can crash your plane by hitting a boat.
