+### [Geng][geng]
+
+[Geng][geng] by [@kuviman] is a game engine that is used by him & friends
+for mostly making small games for game jams.
+
+The focus is to work on the web first (using WebGL1),
+but can also work easily on native platforms.
+
+Font rendering is done using sdf textures,
+which are being created on GPU based on [this article][sdf-on-gpu].
+Some font improvements from February:
+
+- better curve approximation (still can be done better like in the article)
+- use euclidean distance instead of manhattan
+- added a method to create sdf texture for text
+  (previously font only had sdf texture atlas with every glyph)
+  
+Support was added for OpenGL blend equations - e.g. minmax blending,
+which is now used instead of depth buffer for sdf textures
+
+Also, some improvements related to sound:
+API to query `Sound` duration,
+starting sound playback from specific position,
+and changing the speed of `SoundEffect`.
