... best... game... ever...
graphics: come on. its 3d. that alone is an achievement for ANY game on newgrounds. Also, the plant work is a hell of a lot better then some of the other stuff ive seen. (i mean, ive seen green circles with brown lines, and those were called "trees")
style: most original thing ive seen, its own storyline.. touching plot.
sounds: only problem i noticed was the sounds of the hooves was a bit off of when the horse actually was touching the ground.
violence: not much, other then the fact you are dragging unwilling creatures to the demon to be eaten :/
interactivity: you have control of almost everything. you cant get more interactive then that.
humor: the only thing someone would find funny MIGHT be the eating part. and even then, only someone who needs a lobotomy.
more work like this is needed on newgrounds, to be honest. Come out with more things like this.
as the previous reviewer said, it is things like this that are worthy enough to be placed into things such as PSPs and DSs and whatever else you can think of.
hell, make them good enough, id love to see some creator take the idea and stick it on an x-box :P
sorry for the long post. better things are worthy of more words, though.
