Thank you for your comment. We worked really hard to the very end of game jam and had some difficulties making web build.
Unfortunately, because of that, we didn't have time to fix the issue you mention.
Normally, at this point, you won the game, and you should see an ending screen with an image, which is shown at game's page screenshots section. We apologize for the inconvenience.
Congratulations on beating the game! 🎉
