This game looks polished and the concept is great, just the right amount of challenge. I also like that you've made a daily leaderboard that resets, which keeps things interesting. It would be cool if along the way we can use the gold we collect to upgrade, so we can go deeper, carry more, etc.
The movement feels great also, this has the potential to be a great full game, should you decide to pursue that!
Congratulations on the submission, well done!
