Hey, thanks for joining the jam, glad to be making a game alongside you!
I love this idea btw, fighting to the beat is such an underrated game mechanic. Seriously, it feels so good to click to the beat, why do we let Osu! have all the fun..
Hey I tried running your build on the link and it wouldn't get past the black screen for me, not sure if that's what you expected. Since you uploaded a screenshot of gameplay I'm wondering if that's just your local build right now? Anyway, the link gave these errors, if it's helpful:

I could probably help you dig into it more if you'd like help.
Anyways, I'm subscribed to this topic - good luck with the music and chat soon!
