Hello
I have created a simple game in Game Maker 1.4 
It is playable in browser (HTML5). Feel free to play and share this game ;) 

You have 30 seconds to "destroy" as most lines as possible. 
Choose amount of blocks in line by Q W E R (1 2 3 4) and then color by arrows. If you are about sure color and amount match 5th line - hit spacebar to gain points.
It matches? 10 points
No? -20 points.
