I am also a Game Developer! I love to make themed music that fits the game I'm composing for.
Here are a few highlights of works I have done.

happy30 - You Spin My World
A fast-paced piano track made for osu! (Rhythm Game)

happy30 - はっぴークリ (2016)
A Christmas track for an RPG game

happy30 & Sascha Grief - Hanzaki
Eastern inspired track for a mythological adventure game 

happy30 - Supressed City
BGM for a stealth survival game set in a dystopian world. There are multiple layers of intensity.
