3. Gem Craft
Now we’re back to the more usual ‘bad guys on a path’ method of attack but this time the twist is on the tower building or to be more accurate, on the tower arming. You gain mana by killing bad guys and then use that mana to create gems. You can then use the gems in towers or save them and combine them with other gems for more powerful attacks. Gem Craft takes a wee while to get the hang of but adds bags more to the genre than the standard build and level up… well worth a bash, just make sure you read the instructions in the tutorial!
