Hi there thx you for this excellent game. i have a bug and a suggestions to do:
At some point of the game, its become extremely slow, almost stopped. I have all the options to low, no sound and no visual effect. I think it can be a Trap with chain > lvl 2x. Touch a gem during a normal play its ok but in this condition, its freezes the game for some seconds. (the internet radio also stops, i dont know if its because the pc becomes slow or if its has some relation with the internet connection since the game transfer a lot of data to playtomic.com)
Another suggestions is let upgrade the mana pool faster (may be automatic when reach the limit is a good idea) i mean upgrade a mana pool > 1,000,000 its very boring, you have to press M all the time .....
