Thank you both for answering. I guess I won't do it then, because losing my progress would really be sad. Guess I'll have to keep coping with the memory problem. Didn't know 16GB would be filled so quickly beforehand. My next iPad will probably be a bit bigger
Edit: I still did it, now that I found out that using icloud is a lot easier than I thought and a lot of apps use it. Hopefully it saved my progress. Thanks again!
