I got the best ending in Cave Story+ , steam still shows the achievement at 2.2% of the players having it.
Took me a year (i abandoned the game for 9 months before coming back to it eventually). I reached a certain point where you are in that little house and have to go down and do the most mental destructive platforming of all time just to arrive on time to escape. BUT, i didn't know you had to beat a boss too. And not any boss, but the most difficult and terribly powerful one.
