The game isn't meant to be difficult, the way I see it. It's meant to be a good laugh, destroying everything as a giant worm. It's not meant to challenge the player, it's meant to be simple, easy fun. And the upgrades also reflect that - Why would I just want to increase speed/health every time, when I can get frikkin' blood claws, spikes and vacuums - it's all about ridiculous fun.
I think this one was far more fun than the first, a great improvement. Also, the upgrades made visible differences, so I could SEE my worm becoming better and more powerful. The controls seemed fine to me too, with the unwieldiness of them towards the end being not only reasonable, but expected and executed well. I enjoyed this game from start to finish, and will likely play again to choose an alternate evolutionary path.
5/5 Stars
