Clockwatch

A text-based web game for April Fool's, where you can "collect" the current time of day, such as 5:10. You can only collect the current minute, so real-time waiting is necessary. There are tables for tracking collection of different categories of time, such as "Ascending" times like 2:34 or 12:34. There are also achievements for collecting every time in a particular category.

Hardcore gamers will play in real time but a cheat mode is available for casuals.
