ChromaGun is a captivating puzzle game available on iPhone that puts you in the shoes of a tester at ChromaTec's research lab. Your mission is to utilize the innovative ChromaGun to solve intricate color-based puzzles within meticulously designed test chambers. By colorizing walls and objects, including the unfriendly WorkerDroids, you progress towards the exit doors. The game's concept involves mixing colors: Red + Blue = Purple, Red + Yellow = Orange, Blue + Yellow = Green, and other combinations result in brown.

As you navigate through the challenging chambers, you'll encounter doors that require specific triggers to open and remain so only while occupied. If you enjoy brain-teasing challenges and strategic gameplay, ChromaGun offers an engaging experience where your color-mixing skills will be put to the test.
