This game uses a Lua scripting engine and has no sandbox whatsoever. That means [Tamas] can call os.execute, and from there the entire game is over. Or it’s just begun.

If you don't want to learn Java there are alternative SDKs for Android. Corona uses the Lua programming language and it is ideal for writing mobile games.

Aimed at players of all abilities, the set includes software for beginners and advanced developers alike, including Lua scripting tutorials, level design guides, and Blender tutorials.
