I would assume that the development teams would expect you to download the file from the browser rather than the app. I have downloaded this file a couple of times and when I first tried to look for it, a webpage told me that I couldn’t download the file because the traffic had exceeded the Google drive quota because a lot of people had viewed and downloaded it simultaneously. Thankfully, the developer (Poppu) told me of a trick to get around that message by downloading the file after logging in with a Google Account prior to download and sure enough it worked. Of course, I had a few fights with my computer before I got the file to run and sure enough, it ran… Of course, I’m currently in the process of experiencing some technical issues (namely the freezing and game crashing), but the developer and the others associated with the project are looking into the issues the best they can.
