📦 Resources

Code for Music generation in runtime created by author. Some instrument samples are picked from ZzFXM example song Depp

Emoji Font Twemoji Mozilla is used for cross-platform emoji rendering. Game is able to work without e.ttf file, but some icons are incorrect rotation angle, or different at all. But game should be playable anyway.

2D graphics rendering is started from js13k-2d and highly rewritten for what I need.

Sound Effects - ZZFX.
