A retro-port of the easter-egg in Chromium.
It is coded using the When it's done mentality 😀
The graphics were ripped from the original and slightly modified. Some sprites were just 1 pixel too high.
The sound effects were recreated using analysing the mp3's from the original in Audacity. The code for the three sound effects including the sound effects engine is about ~100 bytes. Which is very small compared to the sound effects from the original (6, 8 and 10 KB stereo (but left and right were the same) mp3's).
Remarkable fact: it is 10% of the size of the original.
