xD .
I laughed so much when i heard your voice acting. Great job on this start off for your frame by frame style. I like the sound effects and the music was good. Keep experimenting with little things like this and youll get better and better. And the guy below doesnt know what he was talking about, you didnt use any tweens in this because you dont even know what tweens are hahah. If I were you i would add as much color as possible to your future flashes. I can do some voices for yah as well and help you with any writing, but Tommy is your writer isnt he?
For shooting, you chould have included multiple lazers isntead of just one or two for a better action effect. nice explosion animation, it wasnt too sketchy. And i am not sure how you got this up to 2.9MB... you probably had the sound in a weird format or something, happens all the time.
Keep it up!
