I really wanted to like this game. But the ocean part was too much - I was lagging so badly, even with a small screen and low quality. (And I have a fast computer!) I kept clicking where the fish was and not getting it - you could see the mouse pointer not keep up to where I was moving. You need to slow the fish way down. Or have them pause for 3 seconds in visible places. Up until then it was really great and creative!
In general archers should be the backbone of your army. My standard build is 2 archers, one mage. You should prefer maxing out a single unit (since each upgrade basically doubles its power), over evenly upgrading all three of them. I never build any mele units at all, they are useless. Try to get a lightning mage or a bomber archer early. You want maybe 1 or two bombers in the map, the rest of the archers should be the standard kind. Once you have priests then you need to plan how to cluster your units near it. Build at a distance from the entrance - build about in the middle/toward the end of the map, this gives your archers the maximum opportinuty to shoot. Hope this helps.
This is actually a vampire game, not a racing game. You go behind a car and feed boost from it by drafting.
Then you boost till you reach the next herd of cars – making sure not to run out of food (AKA boost). Then feed some more till you have enough to reach the next herd.
The enemy in the game in not the other cars (they are the prey), the enemy is the road that constantly tries to throw you off, and shake you off of your prey. I guess the road is trying to protect them?
