I seem to be able to figure out all the hard ones up to this point -- but there's just too much to manage in this level... I either can't path them properly enough, or I don't have enough mana to remove the speed beacons and I just get overrun by wave 19-20.
First i put a level 4 gem on the bottom left tower to contain the first waves and to destroy the beacom next it. Them I did a maze of walls using the towers already on the field. And put o tower (the only one i made) on the top left to destroy the beacom. The other two beacons i just destroyed later in game. Use a lot the Focus skill.
I need some help, the game is bugged on the first field with beacons for me... when one of my towers destroy a beacon, the game freezes up, etc. Think the field is d12. I have tried a few different browsers to boot.
@cecilannam: it seems there are many such bugs right now. Did you try updating the flash player? If you have, all I can suggest is clearing the cache, and then clearing it whenever a new version comes out, untill things work.
whoever has troubles with the game: there's a workaround, do an installation of Adobe Flash Player 10.1.83 (NOT 10.2!), go to the site and select "Others" "Archived Flash Player versions", find a 10.1.83 archive below and follow the installation instructions in readme.txt inside the archive. Just tried, it works, and combining gems work, and gem bombing works. Sending a bugreport to Peter.
