I just beat the canyon layer, and it's okay, I guess. It controls really well, destroying stuff feels good, loli Pauline is super cute, and the mine cart boss was pretty neat. But the game's starting to feel repetitive and Void Co. hasn't really left an impression on me yet (though I appreciate that Grumpy Kong, the designated brute villain, isn't stupid). I know I've got K. Rool and the Kremlings to look forward to, but I don't know if they'll be enough to uplift a game that just isn't blowing me away so.
Also the big ugly stone monsters are super lame and pathetically easy, they're even worse enemies than the tikis were.
