I decided to end the experience at 10 Levels. The custom levels start at World 1-1 and end at World 3-1. The rest of the levels are same as the base Kirby’s Adventure game. Decided to do this so I can work on Boxguy Adventure 2! (Plus, I only planned on make 2 worlds originally not 3 worlds.) I may make more minor updates later like bug fixes.

Story

My character Boxguy the Box gets stuck in Dream land because of the mystery of a man named Top Hat Man! You got to help him get out of dreamland by defeating King Dedede and by saving Dreamland, so he can take a nap to get home! (or to go play Somari or something.)

V36 of Boxguy Adventure is compatible with Retro Achievements https://retroachievements.org/game/37009

Also thank you to Savi The Gamer for having Boxguy Adventure in the Kirby Dream Display! Check the Kirby Dream Display out down here!
