I'm fascinated with your design philosophy for this game! The slow-burn was almost too much for me to bear, but it really added to the tension. I will say that many of the objectives felt like it took too long to see a resolution to them. I kept questioning what I was supposed to be doing, and while that also added to the tension, it was quite frustrating. Especially the first one. I almost quit the game because I couldn't find the noise in the backyard. The last little thing is the translation: it's pretty all over the place. I felt like I was trying to decipher a riddle with 90% of the text. I get it, localization of any kind is super tough, and many things don't translate well, but if you get the opportunity to improve on it, I think it will help the game a lot.
This game taught me a lot of tricks that I am normally opposed to doing because of how impatient I am, so I'm going to try and expand my toolbelt and try some of these strong tension building techniques.
I'm also impressed you guys did this all in under 7 days. I guess it really helps to have a team, but I can tell you're pretty experienced too. Great job to your team!
