Yeah, I used to think Cave Story was a pretty meh game and sort of chucked it in with the Homestuck fanbase of being something I didn't like, but man was I wrong.
Played it Summer 2016 and completed it in one day, loved the game so much I just sat down and played it for 6 straight hours. Loved everything from the music to the gameplay, it was all perfect.
My favourite part was the Labyrinth Fight, being with Curly and fighting with her with that music in the background was whack, loved every bit of it. It's my favourite song
on the OST just from the whole upbeat and happy feel to it. Almost like you've found that special someone and it's you and them against the world.
Need to replay it one of these days and get the best ending and go through Hell.
