I finally switched to Game Maker, after some of the problems on Unity when making a 2D platformer. The engine began to be a little too complex, nothing worrysome, but the final nail was the poor performance on certain machines and internet bandwith.

Game Maker is a much easier and light engine, exclusive for 2D games the only problem that I have with it is that, to be able to publish on web or other platorms than Windows/Mac, I have to pay. And is not something cheap, not expensive either but still...

So, I will be working on Game Maker and when i can afford to buy it i will be able to upload my games.

Cheers.
