This game is certainly unique and gives off some good jumpscares,i played this game before the teaser and out of the two i preferred the earlier version, the new teaser felt very cumbersome and your character felt slow and made things less climactic and there was a great deal less to interact with and explore, the previous version although slightly clunky with the ending was great to play and you could move faster and it gave more story and insight into the game and makes you compelled to know more.
If the final product includes all the gameplay from the previous version before the teaser it will be a solid game, i am sorry to say this teaser does not really do as much justice as the previous one.
