Ice Cube Clicker od DuckDev

Click the cube to earn ice shards. Spend ice shards to upgrade your drill, buy automatic drillers, and upgrade the icecube to get more shards when you break it.

This addon is specifically made to be unobtrusive and lightweight. The "gameplay loop" is still being ironed out, and new features such as leaderboards may be added in the future. Ultimately, it just exists as a passive task, something to do while you're in a call, waiting for a download, or letting something compile.
