Good for you on taking up animation! I can see the inspiration for the plot. There's a game shop far from me and it was always fun to come back home with a cool new game. It's your animation, but I'd suggest subtitles instead of speech bubbles if you want people to be able to read what they're saying.

The effort can be seen. Keep practicing, you'll get better! Also, what song are you using? Do you have the artist's permission to use the music?
