It is spam. This is a community site. You've made an account and within the first hour started promoting yourself without engaging in the community as a whole. The only reason you posted was to get hits. Ergo, spam.
Looking through your submissions the only submission you've had is for your game. The only thread you've participated in any discussion in is this one. You deliberately used your age as linkbait.
Try interacting with the community in a genuine way first before promoting yourself and I won't accuse you of spamming or being a spammer.
If you download the game, the in about/credits section It says developed by Nick Shen (nshen) 14 years old.
