Every Saturday at 20:00 UTC

Next jam:

Next weekend (25 - 27 Jan) is Global Game Jam, the largest game jam in the world. Most of us will be doing that instead. If you want to find a jam site near you, go to the Global Game Jam Site. 1 hour game jam will still happen, but expect low participation. Happy Jamming!

I'm a hobby game-maker and instructor, for both tabletop and video games. For 1HGJ, I create retro-styled, 2D video games using Clickteam Fusion. Most of my 1HGJ games are available to play in any typical web browser.

I make most of the sound effects I use with the stand-alone version of BFXR. I use background music from the playonloop.com and gamesounds.xyz websites.

I also post games at www.glorioustrainwrecks.com and my own website: www.let-off.com. Have fun playing!
