Actually, they are based on Eggerland 2 - Meikyū Shinwa (MSX) and Eggerland (Famicom Disk System). I've converted and adapted all the stages, so you can play them in Eggerland Mystery without need to explore a giant labyrinth!

Of course, some stages are less difficult, as the first game of the Eggerland serie has some limitations : only 10 monsters of the same family in a stage, no advanced monsters (Leaper, Rocky, Don Medusa), no grass, sand or lava zones, slightly different behaviour of skulls and golls, no tricky stages. I let you find out the adaptations!

Enjoy!

I'm preparing more new stages. Next package will be based on the fourth Eggerland : Eggerland Meikyuu no Fukkatsu (Eggerland: Revival of the Labyrinth), only released on Famicom. You can expect more than 150 stages !!!
