Hippo Christmas Calendar

The player's objective is to open a virtual advent calendar with 24 doors. Each door contains a hidden picture of a hippopotamus in a festive environment, such as wearing a Santa hat or surrounded by snowflakes.

The core mechanic involves the player selecting a door to reveal the image behind it. The calendar is designed to resemble a traditional holiday decoration, with a countdown of days leading up to Christmas. The player's progress is tracked as they open each door, with a visual indication of the remaining days.

The game is a simple and straightforward interactive experience that runs in the browser without the need for download or registration. It consists solely of a virtual advent calendar, with no additional features or complications. By the end of the calendar, the player has uncovered 24 unique hippopotamus images, each evoking a holiday spirit.
