cgarvie was kind enough to give me a sneak peak at his new level pack.

It install painlessly. Download a file, untar it, run a couple of xterm commands and you are using the custom level pack. After that it is just one command to switch back and forth between the custom pack and rovio's pack. Very easy. All your scores and settings stay separate. There are even a couple of new levels to play with. Very fun.

So a big thanks to cgarvie for letting me beta test.

*edit* I just downloaded the level pack from Ovi. No problems installing or switching back and forth. Now I just have to get through all cgarvie's levels again (I promised to play them and post here today) before I try Rovio's new (or re-released) levels. I've seen one or two of cgarvie's new levels and can't wait to see the others.
