Rainbow Billy: The Curse of the Leviathan is a wholesome, creature capture, 2.5D Adventure-Puzzle-Platformer with over 30 hours of gameplay!
At the heart of the gameplay is a unique "confrontation" system that replaces traditional combat. Rather than attacking enemies directly, you must use dialogue options and minigames to fill the opponent's "heart" with the correct colors and shapes. This encourages you to understand the perspective of each creature and find compassionate solutions to conflicts, rather than resorting to violence.
Catching and befriending the over 60 distinctive creatures is a major part of the experience. Each one has its own backstory, personality, and struggles that you must address through the confrontation system. Leveling up and strengthening these companions unlocks new abilities and dialogue options, giving you ample motivation to invest in and care about your growing party.
Between confrontations, you can freely traverse the expansive, 2.5D overworld. This world is filled with environmental puzzles to solve, hidden secrets and collectibles to uncover, and various islands and locations to discover. The exploration is consistently rewarding, with new creature companions, abilities, and story beats revealed through thorough searching.
The confrontation system incorporates a variety of minigames that you must complete to properly "attack" opponents with the correct colors and shapes. These range from rhythmic button presses to precision timing challenges, adding an element of quick reflexes and skill to the otherwise dialogue-driven combat. The minigames avoid feeling repetitive, constantly introducing new twists and mechanics.
The game includes options to adjust the challenge of both the confrontation minigames and the overall combat experience. This allows players of all skill levels to engage with the unique gameplay, from those seeking a greater challenge to those who want a more relaxed experience. Accessibility options for colorblind players and the deaf/hard of hearing are also available.
