Where do I start?
Let me begin with my overall rating - 10/10. This is not me being a suck-up, this is my genuine score. I loved every part of it.
I feel like GLADoS - "It's hard to overstate my satisfaction."
I can't say it enough - I loved it.
Time for individual reviews.
Music - 9.5/10 - It would be a 10/10, but there was one track that wasn't changed - not a big deal, but I'm sure it would've been a great remix like all the others.
Level Design - 10/10 - there were a couple jumps I had trouble with. but maybe I just suck at platforming.
Story - 10/10 - So many unexpected feels! The ending sets it up for a *COUGH COUGH* SEQUEL *COUGH COUGH*
Side Notes - The characters were very enjoyable and lovable, and (here comes my soft side) ... cute. I loved the choices, often times I was choosing one thing, and then immediately resetting to see what the other option did.
I wish there was a sequel, but hey. Not gonna push. Anyways, 10/10, like I said.
