A variety of tile sets for 2D side scroller mobile games I worked on while at Dexati. These are shown at 300%- original tiles are 32x32px.
Dexati's business model focussed on rapidly creating and releasing . Games would often be built and launched within 3-5 days, depending on the complexity. I would often create 6+ tile sets and level backgrounds over a 2-3 day period when we were working on game projects.
