As the title says, I wanted to work with some tiles. My idea in this project is to create a digital clock design. This is how it looks:

The clock starts at 00:00 and keeps adding 1 second. The exact timing wasn't my concern, therefore the timer may be slower than an actual clock. Remember, this is just a demonstration of manipulating tiles.

I wrote a basic tileset generator in HTML which can be found in this repo. Just design your own tilemap, press Encode, and then use the generated code in your assembly file.
