Unless I’m mistaken, VimJam’s requirement is “multi-use,” so if you think about it, using the same game for multiple jams is EXTRA appropriate. :)
Viewing post in Can I enter other jams with the same game?
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
