I own a few of these Tiny Arcade toys made by Super Impulse, and they live up to their name. However they are still too big to function as a keychain, one of their intended features (see more here), so I made this redesign of sorts. This version is smaller, and has a rounded shape so it will be easier to pocket.
A new feature I added was a key that plugs in and activates the video game, eliminating the need for a power switch. This feature mimics the “insert coin” function from original arcade machines.
