I still need to continue with the first one, just can't get into it. It's beautiful to look at, but while playing I quickly get bored. It's a shame, the art style is very pretty.
I couldn't get into that one until I got the upgraded version. Even then I had it for maybe a year on my HDD before finally committing to it. It had some weird mechanics at first but after a short while, it clicked. Had to get used to creating my own respawn points. Wound up being one of my all time absolute favorite game experiences.
I'm a little intimidated by the sequel because I know how complex it will get and how frustrating (yet satisfying) some moments in the first game were but stick with it. You're doing yourself a disservice if you're any type of Metroidvania or Hollow Knight fan.
