Very entertaining game brought down by extremely poor server performance What should take you 30 minutes ends up taking an hour because half the time you are playing, you are waiting for a server response.
You can get very far in this game without spending a single dollar. I don't find any place in the game where I am harassed for tokens or money.
Fair TD game. Would like to see the price of each tower on the tower tooltip. Same with the upgrades. Not seeing the future research could go either way. I wanted to plan out what my end tree items were, not be surprised.
Like the game. Complains: autopay and medic settings aren't saved so subsequent plays you have to remember to set them. Beginning seems to be a bit slow and there is a definite line you cross where it gets -very- difficult.
