This game is simple yet fun to play. I think some graphic improvement would make it more addictive. Also, some checkpoints would have made to explore more levels as every time I got hit by the red box, the game restarts over. So I'd just collect one coin and skip to the next level :-D Overall, really interesting idea!! With some polishing, it would turn out as an addictive game. Keep it up!!
Also, I'd really appreciate if you play and review my game. Thanks!
