What's new

[Resolved]About the suspension of distribution.

2020-12-18

The distribution of this title has been suspended at this time. We are currently investigating and addressing this issue. We will notify you when there is any progress. The executable files have been modified and the distribution has started again. The Touhou Project program had been falsely detected as a virus by several virus detection services. And the distribution of the program had been stopped because the program was deleted by security in Windows 10. We have reported to Microsoft that it was a false positive, but if you experience the same symptoms, please set the destination folder to be excluded in the Windows Defender settings. (If the problem occurs again, we will report the false positive again.)

(Cleared on Lunatic 1cc) UFO has quite the reputation as being the hardest Windows Touhou game to Lunatic 1cc and for a good reason. But it is also known to be a very enjoyable experience for those up for a proper challenge, as it has even been placed as the #2 best indie SHMUP of all time by the SHMUP connoiseurs of System11 SHMUP forums. The gameplay in the stage portions revolves around collecting differently...
