"Richard Adams, a game developer also known as “Oxygen Addict” is a pretty cool guy. When releasing his most recent game, Invertical, Adams promised that all profits will go to Sick Kids’ Friends Foundation. Invertical is a two-dimensional platformer with a pretty big twist to the traditional mechanics of the platforming genre." - Sam Adonis
