“When thinking about what makes Disney films so good I always come back to one conclusion. It’s that they can be enjoyed by both kids and adults alike. In many ways, Rainbow Billy: The Curse of the Leviathan is the video game equivalent of that. It has the colors and wholesome humor that kids will love but enough gameplay depth for adults to get sucked in too.” 90 – PC Invasion
“Rainbow Billy is a fun and wholesome gameplay experience that’s sure to satisfy anyone with its bright, vibrant charm and tender coming-of-age narrative.” 85 – Cultured Vultures
“This is a game about showing one's "true colors" to the world, teaching that being oneself is the best way to approach all aspects of life. Its messages of love, friendship and self-discovery are inspiring, the sort of Ted Lasso-esque positivity the world could use a lot more of right now.” 8/10 – GameSpot
HEROES COME IN ALL COLORS.
