IMPORTANT:
Due to a drastic programming error, you need to refresh the game after each run in order for it to work properly. Apologies for the inconvinience.
To make it more clear, you can't make assets FOR the jam beforehand. If you have assets before the jam, that's good, But you can't make sprites with the mindset of them being specifically for the game jam. So when the jam starts, and you get an idea of "hey, i could use (insert existing thing of yours here) to make things easier!", it's absolutely valid to do so, as long as you're not simply taking an entire pre-existing project and making it your jam submission.
Everything made FOR a game jam game should be made during the duration if the development time, Though people are usually allowed to use their old sprites and snippits of code from older projects (Small things like a scorekeeper or a common system seen in almost every game). You usually cannot make anything specifically for the Jam, before the developing time starts.
Edit: heres a bit of the rules part of this game jam specifically:
Oh wow! Thank you so much. This feedback was amazing, and this alone motivated me in a great way to possibly make a post-jam patch, free of a deadline. My original plan was to make 10 Floors, with prebuilt layouts, or modularly randomized (like rooms in Isaac). I will DEFINITELY consider a Post Jam Update or even two, And definitely nerf the future floors, and i will also revamp the "get up" system for the wires (at least say it exists). Thank you for your feedback, and thanks for playing :). Happy Halloween.
