<br/>

An easy, light, native game engine running on JVM.

• Why easy? <br/>
  A flappy bird game uses just 56 lines of Java code only.<br/>
  Written in Kotlin, also work on Java, JRuby, Groovy, Scala and other JVM languages.

• Why light? <br/>
  The release build jar is about 1.6mb (with a 1mb Kotlin runtime) only.

• Why native? <br/>
  This engine is completely platform-independent: no JNI linkage, no native methods.
