Was definitily confusing at first (especially without any form of instructions or tutorial or storyline, which could have helped that (and since you submitted over 7h before, you had plenty of time to do so 🤗) but very very good game design otherwise. Great graphics, audio design, implementation of the theme and really nice special effects when changing position in the leaderboard!!
I would say your group is professional or from some gamedev school haha and it looks like you've developed before on GDevelop.
Overall a good game and good job, minus the confusion over what to do then..
