This project was my one of my projects we could choose to do at university. I choose Tetris as I was as a kid a huge fan even though I never owned a GameBoy :)
How does it look like?
I learned a lot, how game mecanics work. This game uses massively CPU when paused, I didn't got the concept of thread pausing / resuming at that time. It worked and it was fun to play.
Look at the highscores.dat where my friends tried to beat my record :P
