I finally got to making a follow up video for this game. Though I only got ending 2 and 3 in this video. I did enjoy how different the story is if you do everything correctly and go to the party.
Amazing game, and I highly recommend people try it out. 馃檪
I don't know if you solved your problem. But I noticed you have to push the direction/movement button towards what you wanted to interact with, and press Z at the same time. Or at least that's what helped me when I was having the same issue.
This was a fun little horror game. I only got to cover the first ending in this video, but I enjoyed it. Would be following up with another video, when I could record the other endings. 馃檪
