Yes, you will probably break the installation of the official level packs if you follow my directions for the pack2 thing.

Actually cg, what I did was copy Level1.lua, to _all_ the filenames in the gamelogic.lua. So my pack1/ contains all the levels that the game could possibly be looking for. I then took that directory and copied it to pack2 _and_ pack3. Since I didn't have the retail version and I didn't know how far to go.

All you'd have to do to fix this to buy the retail levels (If/when they're available again) is to delete your pack2 and pack3 directories (or move them somewhere else - This is of course me assuming that the levels in pack1 that are in themes 2 and 3 will not be loaded from pack1)

After looking at the gamelogic Chunkspy dump yesterday it doesn't appear that anything is missing from the demo except the level scripts for themes 2 and 3.

(I hope this doesn't encourage a re-release with that fixed)

by the way cg, do you hang out in any of the #maemo irc channels at all? I was thinking of starting an angrybirds level editing channel on freenode or efnet or something. I think the only people who would visit would be you and forcer so I haven't gotten around to makin' one yet.
