My first game jam here. Is it OK if I add a base mechanic from another game I'm making to my submissions? And also, thank you for inspiring me into joining gamedev.
Yup. Recycling old code and assets is allowed. No need to make everything from scratch. The majority of the game should still be created during the jam, though. Se reusing a mechanic and maybe some code: Yes. Taking a finished game and just slightly changing it up: No!
