Super fun and creative! This is a really cool concept and creative. One thing that you mastered with the game is replayability, which is extremely important to have in video games. I felt like, after playing one round, that I had a better sense of how the game worked and that made me want to try again and get a higher score. This sense of discovery is perfected really well throughout this game. When I found the golden skeleton after aimlessly picking up near-valueless items, it encouraged me to keep going.
It was super fun adventuring around the city and figuring out a strategy to pick up the most valuable items, and the overall gameplay experience was really engaging and unique.
The art style was also super consistent and fit the game's vibe well. Everything worked smoothly, and the animations were very professional too. Nice!
I don't have many suggestions, but maybe some form of progression or upgradability to enhance the strategy aspect even more? Consider allowing the player to trade some of their hard-earned cash for a strategic backpack size upgrade or a speed boost - the possibilities are endless.
Rich in personality and potential, and quite a fun gameplay experience, wonderful job!
