Recently replayed this game and Oh My God did I forget why I never finished it as a child. I always got trapped on chicken island west as a kid. I did, in fact, get it done! At what mental cost? Yes. Just yes.
My mom likes to play the game still on the weekends, so I get to watch her suffer through my childhood quite often. It's fun! The jump physics aren't great, and some of the endgame tasks are very mid, but it's got my heart a wee bit.
