Two player, Jeopardy! style buzzer game with ATtiny 85

I recently built this two player, Jeopardy! style buzzer game prototype with an ATtiny85 chip.
and thought I would share it with the community. Basically, the players buzz in by pressing one of the momentary push button switches on either end of the board. The first to buzz in, sounds the buzzer for a second and then lights up their LED for about five seconds. The player has those 5 seconds to answer, before the opposing player can buzz in. It's not too sophisticated, but I'm proud of it.

Eventually, I like to have big, whack-a-mole style buttons with internal lighting, instead of the tiny momentary push button switches.

If you have any thoughts or suggestions about the project, please let me know. You can read more about the specifics of the project on my blog: joesgizmos.wordpress.com.
