We deeply understand and appreciate your concerns. ALIS is indeed finished, but we acknowledge that there are still some bugs. However, we have released new editions of the game that address several bugs and content issues.
We are trying our best for the sequel, but we have full-time jobs. Therefore, we can only work on these games part-time, a couple of hours a week.
We want to assure you that our installer is secure and tested. The only reason it's asking for admin access is that we don't have the funds to buy an installation certificate.
