Any one Played this game?

I was just browsing gamejolt and got a game called Brain Buster, the game is in development stage. It includes some really interesting brain teasers.
It took me roughly 45 mins to complete the game. So play this game and post here how much time it took to finish this game. Please don't disclose the answers.
