This is a homebrought game, run on Gameboy Color. Original version: Ian Davison - Tynesoft Computer Software. Commodore 16/Plus4, 1986. Created with GB-Studio 2.0.0 beta5!

Miner Willy, intrepid explorer and nouveau-riche socialite, has been reaping the benefits of his fortune discovery in surbiton. He has a yacht, a cliff-top mansion, an Italian housekeeper and a French cook, and hundreds of new found friends who really know how to enjoy themselves at a party. His housekeeper, Maria, however, takes a very dim view of all his revelry, and finally after a particulary boisterous thrash she puts her foot down. 

When the last of the louts disappears down the drive in his Aston Martin, all Willy can think about is crashing out in his four-poster. But Maria wont let him into his room until all the discarded glasses and bottles have been cleared away. Can you help Willy out of his dilemma? He hasn’t explored his mansion properly yet (it is a large place and he has been very busy) and there are some very strange things going on in the further recesses of the house (I wonder what the last owner was doing in his laboratory the night he disappeared.) You should manage O.K. though you will probably find some loonies have been up on the road and on the beach if I was you. 

Good luck and don’t worry.  All you can lose in this game is sleep.

Thank you for this !

I was never going to NOT do this game once I saw it on your homepage, I am a big JSW fan.

You've done the game proud here - thank you for all the work you do for the scene and the GB dev homebrew side of things.  Really enjoy these classics reborn.

This is my tribute to you...

Dear Gentleman! I am very grateful for the fact that in several cases you make videos of the games I made and promote the things I made with it. In fairy tales, it is usually the case that the good person receives his deserved reward (at least in Hungarian folk tales here in the "middle" of Europe). I would like to ask for your patience, because we are working on getting your worthy reward soon. :) Maybe it will come together for Christmas! Until then, I hope you will delight your audience with more such great compilations, which are constantly expanding. Thanks, and God bless you!

Haha !! Absolutely brilliant and thank you very much.  Honestly love the stuff that you do and thank you for in turn making great content I can show on my channel. :)
