What is Encounter Adventure?

The original game was published in 1983 by Severn Software. It was released for the Oric computer, and then for the Spectrum one.
We heard of it recently on the Facebook group Ordinosaures when the HD version made by Mickaël Pointier was announced. The only differences between the original game and our version are the addition of the word “SCORE” to know how the game goes, and of the word “INVENTORY” to list what you are currently carrying.
The plot
Your task is to find and rescue a young girl kidnapped by thugs.
Everything you need is here but you may have to manufacture some items. Chemistry knowledge helps.
