Well, first of all, before I go on I want to ask you if there are any cool forums likes this one dedicated to C64... and if any if you think that there is a considerable to this community that is aware of the C64
The first game, I seek to find a name, was a game which to had to protect the teeth into someone's mouth and you had to use the toothbrush, dental flosh. If you neglected any teeth they were getting grey and they black... and then to their doom
The other game was a more of a puzzle game. You controlled some machines in a factory that made holes, rotate some cartridges (maybe boards) that in the end had to match the prototype you were given.
