I love game jams and I've partaken in many. I almost always work with a team rather than alone on jam games. Usually I'm a programmer/designer but occasionally I dabble in art, music and sfx.
This is a catalog of pretty much all the jam games that I've been involved in. In the past I've made even more games for jam-ish events but I've not cataloged them here because they either don't exist on the internet anymore or their classification as jam games is questionable.
All the games on this page are either downloadable for Windows or playable directly in your browser. They're all hosted on external websites such as itch.io.
