How to Play Chee-Chai Alien
Quick start
Open a new game and read the search tutorial. In capture mode, use the original GBC infrared input to locate a Chalian. Follow the capture and cleaning prompts, then inspect its entry before choosing a minigame.
Controls
The D-pad chooses menus and creatures; A confirms and B cancels or returns where available. Follow the action prompts within each minigame. Searching uses the GBC infrared sensor's light input, rather than movement buttons alone.
Chee-Chai Alien — About this game
Begin with the search instructions so that you understand the infrared stage before choosing collection activities. After a capture, inspect the creature and follow its cleaning activity. Return to the notebook to compare discoveries and decide which alien to work with next. The rhythm alternates between finding something in a light source and interacting with it through the game's menus and small challenges.
