You have to appreiciate the work that coders do to release games for old systems and the like of pdroms for finding the releases, heres the news:

Squishy the Turtle by cppchriscpp is a puzzle game written for the Nintendo Gameboy. It was originally created in 48 hours for Lundum Dare #34 and updated for MAGFest 2018. You play as a turtle, who must collect his eggs while avoiding the spiders and crabs covering the landscape.
Squishy has a special power he is able to grow and shrink at will. Some places will only be accessible by Squishy in either form. The rivers are infested with piranhas, so squishy must be big when crossing them to avoid piranha bites. Likewise, there are tiny spaces (like portals) that the big, slow form of Squishy cannot fit through. Spiders are also afraid of the big squishy, but crabs seek after him for food. Can you collect all of the eggs and get to safety?
