This is a homebrought game, run on Gameboy. 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 your for your efforts, gotta try! :)

Haha !!!

Many thanks for this, this is a bonus video outside of my daily video releases dedicated to this.

Thank you for the heads up in the channel comments as well - you know I had to make this once I saw you released this version.


Thank you very much! I made the mistake of not including an option so that if you type "gentlemen's pixel club" on the gameboy's home screen, it will either 1. remove all penguins from the game, 2. set that only 20 objects need to be collected. :) But you were very clever, it went much better than the color version! In the game, there is a patform that does not prevent you from jumping and there is one where you hit your head. This also happens in the penguin section, where 90 times out of 100 you will make the mistake of cutting your head into the black platform. :) Thank you very much for this bonus video, it's a pleasure to watch your every gameplay.
