I was able to find these 7 items but need help finding the last 3. I feel like I've looked everywhere but clearly not, hehe
You had to make it an ice sliding level :(. Cool egg design for the ice egg though. Hmm, secret entrance building. I thought it may have been the tall orange one (the one with the body bag(?) inside) but maybe not. I feel it's either that, the blue box at the market or one of the 3D buildings.
I'm so sorry about the ice physics, when playing through it again semi recently I realized that it really sucks lol. As for the building you're looking for, let's just say it outright tells you the time you are supposed to be there
I managed it at least so eh. Let's say it was a challenge. The building was staring me in the face the whole time. I feel so stupid for not recognising it.... Quite a quick ending though seems fitting based on some of the imagery. It was a nice little Yume Nikki - esque exploration.
Thank you for playing! I guess it is very obvious that yume nikki was the biggest inspiration and I wasn't even trying to hide it lol
And as for some of the imagery and the ending, yeah let's just say that I've also had some darker thoughts in my time (most of the things in the game are based on real dreams I've had, which is why some things are as convoluted as they are)
