Which framework for 2D Game?

Hello Guys,

i am new to Unity, in fact i downloaded some days ago the new 3.5 version. A friend of mine told me, i should try out that engine. Also he told me, there are a bunch of real good 2D Plugins to make some cool 2D Games for example for mobile devieces (IPhone, Android). I googled for them and i found three different frameworks/plugins:

• ex2D

• 2D Toolkit

• SpriteManager 2

Before i looked these three up, i found the "Orthello 2D"-framework, which is quite nice to work with, but i got some real annoying problem, i followd that tutorial: http://www.rocket5studios.com/tutorials/make-a-2d-game-with-unity3d-using-only-free-tools-part-2/

I am having a problem however in that for some reason with all of the gameobject (brick/Ladder/rope), if i place several of them around the scene, when i go and hit play they all warp to 0,0,0 so there are 30 blocks that appear as one. then when i stop playing i see in the scene view they are still at 0,0,0 and i have to put them back manually. If i do so, and hit play again, they warp again to 0,0,0. I couldn't figure out, what the problem is, so i decided to look for another 2D solution and found the mentioned plugins.

But one has to pay for them. The SpriteManager 2 costs around 150 & while ex2D has an Indie-Licence for around 35$

Before i invest my money (i am a poor student ;D ) in some plugins, would someone be so kind and tell me, which one should i choose and why?
