I spent some cozy hours during a weekend in the autumn of 2017 testing and improving my pixel art skills by creating a pixel art icon pack with a survival game theme.
The result was a pack with 24 different pixel art icons, each representing a typical item found in a game in the survival game genre.
I distributed the icons for free under the license Attribution 3.0 Unported (CC BY 3.0) on Itch.io.
