"This game is based on Gabriele Cirulli's 2048 (http://gabrielecirulli.github.io/2048/). Actually it's pretty much a blatant ripoff. But, it does have highscores and medals."
The two things that stick out for me are:
- You really could have tried putting an original spin on this, rather than making a clone + leaderboard + medals, and
- Preloader advert :( C'mon, you're making money off of somebody else's idea. That's not cool.
