Pure chance and there's not really any winning strategy or skill to it other than for the avoid all bananas medal. The only skill-requiring medal.
You're just as well to stay in center as the bananas come down randomly and if you race to one side you may miss bananas coming the other side. Then again since it's random it doesn't make that much difference where you are and if the banana isn't extremely close it's not reachable anyway.
High score medals rely mostly on getting lucky enough a good amount of flashing bananas come (some games only one or two come or maybe none, other games you may get like 5) as well as luck of them being close enough to be catchable.
And that's the game.
You can play flawless and still be nowhere close to the upper end medals only because the game didn't give enough bananas or flashing bananas that game. Relies too much on luck.
Not bad. Nice graphics, nice music, somewhat addictive gameplay...I'm mostly just surprised that you're allowed functioning metals in a under-judgement game.
At any rate, I suggest adding in either some form of story, or something by way of either an upgrade system (draw inspiration from 'Upgrade Complete' or other games), or a score board at minimum. In addition, for an 'achievements base arcade game', there aren't any actual in-game achievements, so maybe add those in as well instead of relying soley on newgrounds achievements (especially if you put this on other sites, like Armor Games. Kongregate has achievements though, so...it depends)
Keep on keeping on.
Nice game! I love the fact that it has achievements, that makes the games in my opinion more enjoyable.
Only thing to improve would be variety and the controls. The controls are quite slippery and everytime I go to the left (right) my character slides a little bit and it stars getting hard to control and stop him for a few miliseconds. In other words: try to make the monkey moves "smoother".
You should also add more backgrounds, songs, bananas and so on, it gets pretty boring after a while.
Anyways, good job! ;)
Although this game has some technical skill, decent graphics and not a bad sound, it has absolutely no real gameplay, it is painfully unoriginal, dull, boring and has no story to accompany it
There is no reason to play this game, it is just like every other "collect the falling things" type of game that exists, no innovation, nothing
