The previous weekend I started a game prototype named Mad Jetpack, it is a Jetpac remake with Box2D physics and probably more features.
Jetpac is an arcade game where the main idea was to recover parts of your ship and assemble them to fix your ship while different monsters (from each planet you visit I suppose) attack you.
Game prototype is uploaded and it has already some features implemented. As I don't know if I will continue with it or not I want to share the current state with you.
Objective: pick the small circles(ship parts or fuel) and bring them to the greater circle (your ship), avoid the moving circles (enemies).
Instructions: move the character with WASD, aim with the mouse and shoot with the left button, press 1 to restart the game.
Hope you enjoy it.
