Love the first Infeztation and while it was no breeze to get through I enjoyed every minute playing it. This has the same overall vibe and I appreciate the different approach in terms of look and gameplay. Not better, just different - either way, again, I'm loving it so far.
My only personal issue is that sometimes I forget that the darker scenery blocks (the brown and blue ones) are the same as the green and brown ones and I find myself forgetting that they're solid too.
Great sequel and at the time of writing have finished the first world - now, on to the next!
