Definitely not the best TD game I've played, but still a decent one nonetheless. One can sort of deduce the experience of the game by reading top comments.
The combination of powers that won me the 12 minute Survival badge: Reaper (a must have), Lightning (later it's easier to kill many targets at once vertically), Polymorph (Champions and Brutes begone), Earthquake (delay their progress), Spirit Blade (remember to click between 2 levels), and Soul Jar (you need lots of Mana - usually the best aim is when there are lots of builders coming in from the side, or at the middle when the tower is quite high).
Running just so you can see colors; I think this game is more inspiring than entertaining. Us color-seer should be grateful. Oh, and also envy spiders (they see 4 basic colors).
A lot of people give this game 5-stars because of the "storyline", huh? If this level of creativity could get you 5-stars, maybe I should start writing fantasy novels.
Be grateful that the police gummies decided to just run along your bouncing path, instead of shooting up (though getting shot should get you to move faster in some other "launching" game...).
