awsome game
when using homing arrows lvl 3 use hold controll mode... because yo just need to click to fire, otherwise, use drag control because it takes to long to fire normal arrows with hold
i tried pretty much every combo and by far... homing lvl 3 + lightning lvl 3 controll option owns (except for the boss... there homing + piercing is better.... because you won't get time to circle around him and shock him because he's like big)
other interesting combos: homing + time (just for dinosaurs)
- piercing + fire (early ingame... this one is good because it's cheap and works well even if you don't have fire maxed out)
- in free mode (after you finish the game) use homing + everything (just for fun... most combos make some very nice visual effects... it's so fun to see the enemies going randomly after the gravity arrows...)
what NOT to use:
- teleportation, lead and helium... because you rarely get money for kills (teleportation lvl 3 can move enemies out of the playing field)
- traitor arrows - the corrupted enemy takes way to much time to act, you will way too often kill the one he's after, it takes ages for him to move and he then comes back at you
