I might go back now to add names real quick, if only for reference, in the blogpost.
Also Pro-Tip: if you don't see 1-2 of their games on their DLsite page when browsing (such as the 14th, Reversi of Temptation; although idk why one would be looking for that one specifically), use a VPN and switch locations to Japan (with a recent change in DLsite administration, plenty of titles with risque-er tags became Japan-only).
For a completely Free easy-to-use VPN, I recommend SoftEther VPN, link to it
You must be registered to see the links

You just download the installer, install it, click on "VPN Gate Public VPN Servers" option from the list (2nd one), then choose one of the connections from the country you need (you can look for higher internet speeds there), then you're Gucci
