Just finished this profile after a long time of on/off work. It's an indie metroidvania made by Chronicler of Legends (shoutout to them as their help in making sure that i could test on the full version was essential by the end). This should cover the entirety of the game apart from a couple of cutscenes near the end but I'd call this 99% done and unless i bugfix and come back for the couple of minor bits near the end, it's likely the final version.
Verified working with both full game and demo rom available HERE
sidenote: select and B will reset the camera.
