Nekonyan's next release will be Riddle Joker on the 18th of December, so we'll have something new to play over the holidays which is always nice. More Yuzusoft Moeges . Havent completely finished Senren yet though lol.

I wonder if they are having issues with Hello Lady's engine or something since the base game has been done for months now and i believe even the fandisc is almost done (already TLed/Edited), hopefully thats their February release
