DexterNeptune - there is a way, in the top left of the screen there is a little "options" menu and you can choose to disable "control reminders" there...
alexislag - razor queen is the strongest gloople. it may come at ends of nests (if you want it to come, almost clear a nest - leave about 5 glooples and then just wait)
Great game, but the only con is AI. I really hate when my teammate attack a heavily shielded unit or even worse, a unit with the damage/heal reverse buff XD...
I really like this game, but it should have more cards (otherwise it gets boring after a while), be more balanced (currently it contains many broken cards, especially Vanessa Voss and some others), and I think you can also add an option to trade cards with other people.
