Edia's 'Tenshi No Uta Collection' was released yesterday on the Nintendo Switch eShop in Japan, as planned.
As stated below, this new compilation release is the latest in the company's ongoing Telenet Revive series and contains the first two Tenshi no Uta games — Tenshi no Uta and Tenshi no Uta II: Choice of the Fallen Angel. It was crowdfunded earlier this year on the Japanese website Makuake, where it raised 11,979,600 yen, and is now available to purchase for 5,280 yen from the Japanese eShop.
Sadly, there's no news on whether the game will ever be offered in the West and currently, it only features Japanese language options. So, all we can do at the moment is cross our fingers and hope that someone picks up the rights.
