Hi ! I'm currently developing a 2D arcade-like top-down space shooter game. The basic rules are as follows: In order to reach a new planet, player will have to collect coordinates on current planet. To reach current planet, player will have to defeat its fleet (enemy defenses). It should also be noted that: There will be a boss at the end of each level. There will be a checkpoint after each wave. The player will have the ability to collect the following items: Health after breaking health containers – health floats to the ship regardless of its position (animation) Ammo after breaking ammo crates – player needs to get close to ammo in order to collect (magnet) Credits after destroying enemies (including asteroids except explosive ones) – credits amount depends on enemy’s power/health Crystal matter after breaking crystals – amount is random (with boundaries) This is pretty regular and I'm looking for additional original ideas to make it more unique. The game is intended as a smartphone game using touch controls. If you have any suggestion, comment, or would like additional details, go ahead! I could add more details to this description but I don't want it to be too boring. If something isn't clear, I'll be happy to answer your questions.
