Humans and their tens...
Why does everybody give 10s out to every other flash!?
No offense, this game was addictive fun, but worthy of a perfect score? I think not.
Concept 4/5: Pretty original, a good idea.
Graphix 2/5: Meh, nothing special. I know this isn't really a game that needs great visuals, but the explosions were a bit disappointing. I would have LOVED some flame effects and better, bigger explosions for chain reactions.
Sound 3/5: Again, the chain reactions could have used a little more "KABOOM !!"
Controls 3/5: Nothing wrong here, sometimes just seemed a little too loose. But, hey, it's a helicopter.
Entertainment 4.5/5: This game is very, very fun and addictive. Great time waster.
Overall, this was a wildly fun game that lacked detail and got repetitive. Still really cool, though. Add some more specialness for chain reactions, and some more detailed graphics would be sweet. Also, maybe some powerups, different helicopters to hit and pilot, and more interesting environments.
Pretty good game with room for improvement. Nice job, I hope you make another one.
