May the dinosaur be with you
Alright, so I have just finished the first level on Insanity difficulty. First, I'm gonna commend you on the difficulty increase from Medium to Hard to Insanity. Yesterday, I started with taking on this level on hard to get back into the game, and then dropped back and forth in-between hard and medium with the challenge mode enabled, as the burrowers lobsided me near the end of the level a couple times. Now, after having to reset and rebuild my nest structure about 5 times, I've taken down the level on its second hardest (or third, depending on how hard Hard Mode With Challenge On is) difficulty, and I think you've struck a wonderful balance in the amount of food, amount of enemies and placement of strategically vital resources on the map, and in return, it works wonders as an introductory level for the game.
