Same as the rest
I don't see the fun in this. It would be okay if we could color, say, several animals, then it might be an okay children's game. But why would we want to print and keep a picture of an envelope with random colors on it? However, the technical mechanics of the game do work very smoothly.
Honestly, I couldn't even see the point to this. Coloring a letter isn't fun or interesting to any degree. It's overly-simplistic, mundane, and far from creative. You gave the player only three things to color anyway. I wouldn't want to print something this simplistic anyway. I will give you credit on the amount of colors you were able to have, but otherwise, nah. I don't see the point.
Coloring an envelope just not my thing.
I know this flash directed towards a certain demographic but coloring an envelope just isnt for me. I believe this is the second color X I've seen by you, so instead of just offering a single flash program that just colors one thing maybe something that has a selection of things to color that you can choose. On the plus the music is nice and the selection of different colors is a super plus.
