Lo-Fi Games

Hi,
Just a quick question if I can, I downloaded a demo of 0.67.2 for my 7 year old HP laptop and have been playing it for 2 days. It is great. The new Steam version I bought today and downloaded on my new HP all-in-one. Which is graphically just beautiful.
The question I have is, is it possible to get a key for my older laptop running 0.67.2 because it can't run the new version. which I can take to work with me and play during lunch.
While leaving the new version on my new HP to play when I get home at night?
Appreciate your time and for the very cool and interesting game, though I keep dying, but I am working on that.

your current key should work just fine

Thank you for the help. I appreciate it. I think I will have to ask Steam though, I don't know where the key is. Unless it is on the receipt when I bought it. But that is a guess at this point.
Anyway, thank you for your help.
Have a great weekend

Looks like all I needed to do was select the version, in this case the oldland 0.74.2 version and then install.
It worked fine.
Thank you for the help and have a great night.
