This might be a good game for kids at Xmas time, but I'd venture to guess that the low score is because either the instructions aren't clear enough, or the game just doesn't work. Clicking on matching, side by side icons doesn't clear them. So what do you need to do to win. Is there a minimum number of matching images required? Clearer instruction please.
Chrome users will probably lock up on loading. The fix is to click on your options and select MORE TOOLS. Then select TASK MANAGER. Then find the Unity Player Plug In and highlight it, and end the process. You'll get a notice that the process has ended, so select to restart it. That should get you up and playing.
I had exactly the same problem that RainbowRhyme had. Refreshing the page also solved mine. I tried to recreate it but couldn't. So it's a minor issue, but it might turn some people away.
Yes, it had some glitches, but overall I enjoyed it. Hopefully the designer will learn from this effort and improve with version 2. And who cares if it's a clone of another game, provided it give the player the same enjoyment. There are rarely any games that don't use a concept that we haven't already seen.
