For those who were asking: When you save 500 DNA in addition to maxed stats, your occasional speed burst (used when you press SHIFT) also gives you strength like the strength flowers so you can power through Stegos and Triceras as well as small boulders. It's essential for even having a chance at Twin Peaks on Insane. It took me 20 tries even with those upgrades.
This is the single best game on Kongregate for replay value!
Some tips if you're going for milestones:
Speedruns are often the easiest way to get totals. Play the level with raining lizards to max your lizard chomping easily. The best level for birds is Planet D on Easy. Worms and Runners will come with time. Worms more time than Runners ...
The best comedy is subtle ... but that doesn't make it simple. This game, like the first Cactus McCoy, delivers a cartoon atmosphere without skimping on good game control and clever level design. It's rare to find a Flash game with such a smooth interface -- but it's even rarer to find a Flash game with the subtlety to be effectively comedic. 5 stars.
I'm a veteran of strategy games, both from the design and from the player side, for 20 years. After about a month exploring this game, I'd like to leave a compliment for the game designer.
A really slick, well-themed, well-balanced, FUN card game. Kudos to you, this is one of Kongregate's best for sure. One of three games on the entire site I've given 5 stars.
I have played around 100 games on Kongregate, and I have rated three of them 5 stars. This is one of the three.
The gameplay is fluid. The art is fantastic. The theme is innovative, refreshing, clever, funny. The music is spot-on. The replay value is tremendous.
This is an excellent, excellent game.
One of 3 games I've rated 5-stars and the only one on this website that merits a comment.
This game is the best example of elegant, simple design I have yet seen. It deserves to be called more than a game -- it is art. Outstanding.
