Need new levels and fixes – Symbol Link - Game Challenges Review

We need new free levels (or entire pack), or just make one of the paid packs free. I haven’t seen any major updates or new features (other than annoying or confusing ads) since this game was listed on the app store. Also the game crashes or gets stuck and doesn’t respond after a few levels or clicks within the game.
