Instructions maybe...
At first I thought the balloons wouldn't pop for me. Then I realized that this is a color matching game. But I had no idea how to change the colors. It took me smacking the keyboard around until something happened. Apparently, hitting "T" gives you instructions. Then I realized the space bar was for changing colors. All of which I had to figure out on my own with no instruction.
Can you see the confusion that went on here?
