PortabilityPortability

• C++ layer is portable, runs on C++ layer is portable, runs on Windows, Linux, Mac OSX and iOS Windows, Linux, Mac OSX and iOS ( and android, but not fully ported )( and android, but not fully ported )

• JS layer is portable, can run where JS layer is portable, can run where ever there is Javascript available. ever there is Javascript available.

• Games are portable, the API is shared Games are portable, the API is shared across platforms so the game code is across platforms so the game code is abstracted from the platformabstracted from the platform

Fun!Fun!

• Writing the game I always wanted to Writing the game I always wanted to build required certain features. This build required certain features. This game needed an engine, rapid game needed an engine, rapid iteration, all of which over time - iteration, all of which over time - became something that I now call became something that I now call Lab2D.

Mostly about 6 months of 'experimenting Mostly about 6 months of 'experimenting with libraries' while working on the with libraries' while working on the game in my spare time led to the base game in my spare time led to the base features.features.
