Domino Frenzy This system is solid
But your execution on how to use it lacks innovation. I found myself more frustrated then anything else during arcade mode. Having to set up a certain amount of dominoes in a certain time frame is more of a chore than anything else. The Free play, however, was more intriguing. I think if your gonna make a game with this awesome system of yours, you need to be a little more creative then the whole time system. The levels you had were nicely done. The music waaas...annoying...i was rushing for an options panel when i realized there wasnt one, and had to turn the knob on my computer down. I gave you a one for humor bc i think everyone gets a little giggle out of pushing a domino down and makes their hard work pay off.
For improvement suggestions, I'd say during freeplay, allow placing other objects, not just ones to avoid but some to interact with. Id say during arcade get rid of the time feature and maybe make it so that the dominoes all have to hit key points, and must hit them all. This domino engine is really really good, you should think a little more outside the box and reinvent the game. I hope you take this review constructively.
