Twinstack

[b]twinstack[/b] is a less conventional take on tetris. not only does it play horizontally, but shapes are coming from both sides. after placing the first in the middle, the rest can only be stopped by other shapes and the game ends if either edge of the screen is reached. [b]2 game modes[/b], single and dual. the former alternates sides and there's only one piece in play at a time, the latter has you controlling pieces from both sides separately but at the same time. good luck... the next piece on both sides is shown, points are only awarded for clearing lines. controls are the usual, wasd and/or arrows to move and rotate, but [b]since it's horizontal, left rotates, right speeds up movement or vice versa[/b] if the block is coming from the other side. space doesn't drop the current piece. it needs getting used to for sure and it's very much a balancing act. if you keep clearing lines on one side, the whole thing moves towards that edge, and clearing all the lines leaves you with not...

Do you think you've seen every possible take on the Tetris genre? Do you think you've mastered them all? Think again. Excellent twist on the classic puzzle that pulls no punches, between splitting your attention and the use of several challenging 5-block pieces. I haven't tried the dual mode yet, that must be fiendish! The graphics at maximum settings are very pretty, but some of the block colouring is too similar to the background making the pieces a bit hard to see. It's a minor inconvenience, but it would be lovely if some of the green hues were changed into, say, blue or something that stands off more. TL, DR: great little game. If you like Tetris, try it!
