You could have submitted! I allow fixes for game-breaking bugs after the jam is over. Looks awesome, will def. check it out! And a few other people were also having issues with json files, wondering what's up with that.
oh that's strange, I did submit it originally but then on the game page it said that I couldn't upload a new file because the jam was closed.
And yeah I feel like the Json thing is just really easy to forget at the last minute haha
