Suggestions for a sequel..
Blasting Agent was fun for an hour and I thoroughly enjoyed it . BUT, I see your score is kind of low, and I think I know why...
1. Add more than just 2 difficulty levels.
2.. More levels, and with more vibrant/varied backgrounds. This one was over too fast, and the backgrounds were well drawn but bland!
2. Increase # of power ups for the gun, and have the graphics of what it fires change even vastly as it powers up.
3. Awards you can choose between to create a unique feel to your character, so each time you play your fighter becomes unique, without it...why even bother replaying?
4. Add more music!
Kudos for making this game and I hope to see a second installment with a daily 1st place soon!
