final boss should be badspot
then once you "beat" him (not really) he stays alive and the game proceeds to tell you it's hopeless, then you get banned. the game ends with you in a totally black area where you could only see your player. you could improve on this idea if you want.
You/Your player starts to walk in a straight line. Suddenly, he/she/you drop/drops down into a website. After looking around, it's the Blockland home page. He/She/You notice/notices there's a door leading to the shop to buy the game.
He/she/you know what you have to do.
-new game + mode?-
i don't know it's a crappy idea i came up with
