anomaly 2 on the ipod touch 5th gen

I managed to get anomaly 2 on the ipod 5th generation, by using wi-fi and then downloading anomaly 2 on my ipod . On the description it says the game doesn't support the ipod touch 5th gen, so should i delete the app in case it jacks up my ipod or is it something i shouldn't worry about.

Note:I only played the prologue mission so far, and everything runs smoothly and the graphics are good.)

Any answers would be appreciated

 

Okay, thanks for answering, The only reason i got anomaly 2 on my ipod is because i purchased without looking if the game supported it, otherwise i would never attempt something like this. Anyway, thanks for relieving my concerns

 

I tried downloading anomaly 2 using the iTunes on my computer. it doesn't work, every time I try to put the app on my Ipod it says
anomaly 2 couldn't be downloaded or something to that extent.
The only way I have found how to get anomaly 2 on my ipod is to get wi-fi and then go to the app store and download anomaly 2 on there.
