If I wanted so many ads I would Tivo comercials.
Good:
-Haven't seen this type of game before
-The three modes offer nice variety
-Display is nice and clean
Not so good:
-When a game ends it would be nice if the "next round" button was a "return to main menu button" (yes, I know that right now you need to press quit and that it tells you to do so)
-Music (a single song is OK, but it's tough to pick something that 1) everyone will like and 2) you can listen to it for a long time without it getting annoying) perhaps you could have a few different tracks in the game and allow the user to chose which he wants.
-I would have preferred an add and subtract button for each color rather than just having an add button.
What makes the game unplayable for more than 5 minutes:
Ads. This game is fun and interesting, but the ads ruined it for me. Each game takes just over a minute and the reward for completion is a 20 second ad. On the games main page? A large, dominating ad.
I saw your comment to the one reviewer that if you play on a different site you can play without ads. Welcome to Newgrounds, that's where I played your game and that's where this review comes from.
The game-play is fun, but not enough to justify so many ads or make me want to go to a different site to play it.
0/10 0/5 Because the ads made it unplayable and unenjoyable for me.
