Let me first and foremost say that this is now one of my all-time favorite games on the iPhone. While it lacks in any sound or sound effects the gameplay is very hands on and the random levels are challenging and leave you wanting to go back and replay it more and more.
Suggestions for future updates:
- Main Menu (ft. Play, Resume, High Scores, Settings, Help, Exit)
- Sound / Sound Effects (but still allow the user to control these in a settings panel so they can listen to their own music)
- High Score (show both local and global leaderboard)
- Help (listing of the types of enemies, and listing of powerups)
- Add powerups (multiple guns, explosive charges, lasers, seek-n-destroy missiles, planetary pulse, planet life boost, allied ships providing support)
- Alternate Modes of Play (ex. Timed Challenge... complete a mission in an alloted time)
- Challenge friends directly or at least offer and "email a friend a challenge"
- Look and Feel (the blue and red of the game is great, but you need to have a tighter adherence to the style in the pause button and high score screens)
Keep up the great work and looking forward to seeing how this app develops out!
