I thought I would leave this to the devs but since they aren’t responding I’ll just do what I can to help. First of all: Are you playing on a Windows computer? If you are I might be able to help
First thing to try: Click on the search bar in the bottom tab and just search up Paper Lily. This is because you could’ve accidentally downloaded it into the wrong folder
Second thing to try is to use a different browser. I recommend Opera or Firefox.
Third thing to try is to the check what version you are downloading. For example a 32-Bit computer runs 32-Bit apps, but a 64-Bit computer runs both 32 and 64-Bit apps(in this case the version named Paper Lily Demo v1.0.4-WINDOWS without the 32BIT) So if you’re not sure what version to download just download the 32-Bit one.
If that doesn’t help then please send what the permissions ask
And also, for the future, it is not the smartest choice to close games from the bottom tab, instead press Esc(for most games), and there click Exit or Quit
