Specifically I'm considering entering Vim jam as well. The timing of both jams is pretty similar and Vim jam does allow this.

Can I enter other jams with the same game?
Absolutely, as long as you follow all rules and time limitations for each jam. Note we lock submissions, so you won’t be able to upload new builds while this jam is being rated.
I’m not sure it would work if it was used as the only multi-use mechanic, as that might be seen as kind of a copout, but I think it would be funny to acknowledge it as long as the game had an actual gameplay-related multi-use mechanic. (But it would be awesome if you could somehow tie the two together—like a Legend of Zelda: Oracle of Ages / Oracle of Seasons type deal where each game can be played on its own, but they change into something else if you play them both.)
Well hey, one game jam is better than none, so congratulations! :D I just gave it a play/rate/comment, and you did a great job! I realize the voting period ends in about an hour and a half (I had some things come up and didn't really have time to play any other jam entries until now), but to the extent you're rating games in the final hours of the jam (or just feel like playing more games even after the voting period ends), feel free to check out mine! https://mycousinjimmy.itch.io/bear-with-me
