You can, but the build(s) you post for the jam should be free to play.
Viewing post in Long running game project
Hi. I also have a long-running retro game project, Back to the Arcade, but I'm not sure if it qualifies as 32-bit. It was originally created as a 90's inspired retro fantasy console on which you play remakes of classic arcade games. I didn't want to submit it without checking first it it fits in with the 32-bit aesthetic and spirit of this jam?
Thanks for your reply :) Yeah, the idea of Back to the Arcade was to make kind of 90's inspired remakes of 80's classic arcade games with a holographic twist. And I think I want to keep it limited to just classic arcade games for now, which probably doesn't quite fit the brief of this jam then. But thanks again for your reply and all the best for the jam! I look forward to seeing everyone's work :)
