Oh my goodness Cat, thank you so much for saying so! I see you've submitted something, and I think that's incredible!
I apologize for not getting to you sooner (in fact, I've pretty much disappeared from this whole jam, which is disappointing because I was so excited to launch it!). I was going to tell you that late entries are 100% accepted, so if you wanted more time it would be totally okay :D But you did it anyway, you made it! I'm actually finishing a game myself right now lol whoops.
The offer stands, though: if you want to take some time to make something else and enter it, feel free. Or if you want to update your game after it's entered, also feel free! The only downer would be that it might get rated before then if already submitted, or might get rated fewer times if entered late since it means fewer days for people to rate it.
This is all for fun, and even though the entries are rated, I really want that to be more about celebration, not winning. We're all winners for doing our best (or even just doing what we can with the remaining energy we have after a rough day/week/month/year/decade lol).
Also, more specifically: tools, pieces for other games, etc are 100% acceptable, and I LOVE the idea of using music to develop a character!
