This concept has been done before, usually with fish eating smaller fish, so it's not really an original concept in that sense. If we compare it to those types of games then there isn't much to say. Graphically these games look better and the controls are smoother and they tend to have more different content.
I did, however, like the way that when you get to a certain size the game stops and you get told how well you've done, but that's all I really liked about it.
But sadly the controls are not really enjoyable. If you let go a key the circle still moves a bit making it really hard to dodge at the beginning.
The difficulty pacing also is not optimal. It begins with "Hard" and ends "totally easy".
Also the hitbox of the circle seemed to be bigger than the circle itself it happened to me a few times tat i bareley evaded a square (but didnt touch it) and still got hit.
Ahh and perhaps make the screen bigger. It would be more fun with more space to "play on". ;)
Conclusion: I like the idea and the concept but it need really some work.
Need levels and increasing degree of difficulty
On a computer, this kind of game do best with the mouse as the primary control.
Perhaps a mouse makes this game "too easy", so maybe compensate that with a slowly increasing degree of difficulty and make it last longer, maybe add levels into the game.
On the other hand, with key controls this game could be easily ported to mobile platforms such as mobile phones and PDA's.
But then again, the game feels a bit ... short?

unoriginal short and not very fun sry dude
Damnit. Who uses arrow keys or even wants to use them anymore? Most gamers have swapped over to wasd. Using arrow keys feels alien these days and isn't enjoyable. Although the concept isn't bad, the controls are very. Either mouse or wasd keys please!
