For a first game,
It's okay.. but the ad was annoying, and the game is way too simple and easy, one could simply just press random arrow keys and still eventually complete the level. It has no music, which is another huge downside, and it had no other elements at all except for just moving around squares. This could use a lot of work. I didn't think you used a great choice of colours either, but the timer seemed to work well. I don't really like the idea of being timed to see how long it takes for you to complete the game, but a timer in each level could work, but still, you need to add more elements to the game. Also, you should really make the main character be the one moving around, and not just a little blue square, I found that quite boring. One of the major problems with this game is it requires no skill, and there's absolutely no way to fail, or lose. There are no enemies, or traps, and no bonuses either, just squares, which got me bored quite fast (and I did play long enough to see if there was anything else in the game). Considering it is your first, this isn't too bad, but I really hate when games have those ads in them, please make your next game lack an ad, I have deducted a star for that. I think overall you deserve a 6/10 for this, since it's your first, but it still needs a lot of work.
