Feedback from the experts

Abiyasa Suhardi: A very interesting concept and well-executed game, exploring an OS-like environment, looking for clues and scores. It’s like multiple games inside a game! Quite amazing you can fit them all in 13kb! This game has trophies, scores, points, and secrets to explore. Also, it stores the game progress so you can continue exploring on another day! Very addictive. It’s well-polished as you can see the details on small things: icon, music player, and nested-games. Has good readme on the GitHub page and good sense of humor too :-)

Joep van Duinen: Impressive that all of this has such a small file size. Nice sense of humor. We love the Japanese voice. Enjoyed a lot the snake game Make the games more visible - access to the desktop maybe?
