Ninjahtic is an action/adventure platformer with elements of puzzle-solving and stealth. While it's progression is linear, the open-ended nature of every level requires exploration of an abandoned civilization located atop floating islands.
My latest release, entitled Hikikomori No Chuunibyou, had been Greenlit and is now available on Steam!

Like all of my other games, I developed it in its entirety on my own as well as having had composed the soundtrack.
