It looks like the game is not actually up on the page, there's just a still image.

Oh jeez, I'm so sorry about that you're right. I thought I pressed the esc key but I guess I didn't. Your game is working fine! My bad.
It's an interesting concept. This time of year, I'm very familiar with the feeling of struggling to buy gifts for people.
At one point, I thought, why isn't it letting me buy this item? Oh, it's because I spent like $30 on chocolates for my mom and I have no money left XD. I made my family reasonably happy, so that's nice. Maybe if you try to buy something but you don't have money there can be an error sound or a notification that you don't have any money.
