(*my english its bad but lets go*)
Sure that he wrote too easy is because he did nothing and wanted to leave a sarcastic review.
I will give my review, I think the controls are super uncomfortable although of course this is the challenge of the game, but you almost have to leave the screen to be able to attack the birds the mouse you have to up to the top of the screen or do not get them to shoot.
Some extra things that would improve the game:
At the beginning about 30 seconds of some story line
Storylines are always important
Example
You're Drancon, an old volcano. It seems that some water monsters decided to attack you.
You can draw an old volcano that is asleep but going up the beach towards the mountains are those little things that want to hit it.
you see? Something as simple as that would greatly improve
Among other things I quite liked the game, although the waves are very fast and as I said before the controls with the mouse very uncomfortable
It is noticeable that he has much effort and dedication
Luck and hope more games of you
