A very light game with a couple of pros and cons.
First the pros: Easy navigation with only one arrow key (up). You can easily position the block by using left and right arrows or speed up by using the down arrow. Nice stats screen with current and all time high scores, plus the level indicator.
Now, the bad. It’s a beta version, which means it got never improved. Very basic graphics.Link at the bottom (don’t like such tricks).
In the end, it’s Tetris. What’s there not to like.
