The visuals are amazing, as well as the use of particles, the use of musical notes to guide the player as well as the monologues easily adds up to a classical mystery game. The game design is pretty solid in my opinion, the only issues I might have so far is the use of the effects, not that it's bad, it's just heavily slow on my browser, which sort of proves that eventually, it will have a much stronger foundation on a pc or mobile release.
Can't wait to see more of this even when the jam is over ;)
