I'd testplay it if it's a webbrowsergame, while the first look (of the images) lets me think of tetris-blocks stacking up? & the video sounds more exciting about reusing blocks onscreen, than filling lines by upcoming ones.
Sound fits to a calm game like that one, also grabbing a block can be just one of the most top line for a reaction to nearby blocks underneath/left/right ...than a "connect four"-gamingtype. I see no timer just a score which suits to no stress and its music in the background.
A question came in mind: when will a new grey line appear? Affected by the amount of vanished blocks/rising points or if just a few amounts of blocks being ingame somehow?
