i plan to make a game with electricity as a secondary mechanic, however i may not be able to implement it within 3 days, should i not submit?

You can also submit an unfinished game if you still like to share it, or if you need a little bit extra time you can request a late submission link.

if you can't implement something relating to power, that's ok. to quote the jam page: "Remember, theme is purely inspirational and not required
