Iridescent

Cooperative puzzle game for two players who collect and mix colours to get past obstacles.

About the project

A 3D split-screen puzzle platformer for two players, made by a team of three for the Game Development course at FIIT STU in 2022. Students from the Academy of Performing Arts in Bratislava contributed 3D models.

Each player carries a colour. Players collect colours in the level, mix them into new ones and use them on obstacles that only react to a certain colour, so most puzzles need both players working together. A playthrough takes about half an hour.

I was responsible for the obstacles: buttons, levers, doors and the special blocks the levels are built from. I also built most of the second level and fixed bugs in jumping and collisions. My teammates handled the player controls, colour mixing, camera, menus and the other levels. The game is released on itch.io for the browser, Windows, macOS and Linux.

What you can try

Local co-op on one screen, with keyboard or Xbox and PlayStation controllers
Colour mixing: combine collected colours to unlock obstacles that need a new one
Doors, buttons, levers, shadow blocks and destructible walls that react to colour

Highlights

Push buttons, timed buttons and levers that only react to the right colour; bigger buttons need a player who has absorbed several colours, and a cube of the right colour can hold a button down
A button stays pressed while anyone stands on it, and lets go when the player on it loses the right colour
Doors linked to any number of buttons, and one button able to open several doors; a door stays open while any of its buttons is pressed
Coloured doors that only a player of the same colour can pass, shadow blocks on a timer and destructible obstacles, all as reusable prefabs
Most of the second level and the last checkpoint of the first one
Fixes to the double jump, walking through walls and buttons pressed by both players at once

Both players standing on pressure plates in stone ruins — Many puzzles need both players at once, for example on two pressure plates.

A see-through shadow block next to a player on a button — A see-through block that turns solid while a button is held down.

Red player next to a blue colour source in a wall, the other player still colourless — Colour sources in the walls give a player their colour.

Blue player next to a blue see-through area of water with a ball — Obstacles only react to a player of the matching colour.
