Hope you like the free movement + mouse aiming idea implemented in a Touhou game that I got back in October 2019. The game is far from completed, but the "engine" is 75% finished.
Thanks atTAMUSIC for let us use some of their soundtracks and at yummimaichi for their awesome work, both on Twitter.
Finally, thank you for giving it a try. Hopefully the game will become a novel in the Touhou series ;)
