3-in-1 game

Background
I had made an 8x8 LED matrix earlier. I also had made a kind of a keyboard. Both of these were purely for testing purposes.
Some day I saw the LED matrix and wondered what if I wrote a game for it. One idea lead to another and now there's three games for it.
The design
There's no fancy designs for the project. Just a simple LED matrix and a self-made keyboard.
The project
The project was simple to write three games for the hardware I had made earlier. The three games are:
- The snake
- Ping pong
- Space invaders
There's a video of all the games. You can see it below. While editing the video I noticed a bug in the ping pong game. Can you spot it?
End result
I'm pretty happy with the end result. Especially, the Space invaders is a cool game. It's my favorite.
And what's the most important thing in this project: I had fun time doing it.
