Yet more goodness from the Australian games development scene, with Letter Stack from Push Poke.
Letter Stack is a game about creating words by playing letters in a Tetris / Columns style fashion. You stack letters on top of one another at breakneck speed, aiming to spell words in amidst the chaos.
It's a novel game, and a worthy first entry out the game for developer Push Poke, the founder of which is an ex-Zynga studio CTO who has recently moved back to the indie scene in Sydney.
You can grab the game on iOS on the App Store here.
