I've just finished playing this game, and it is awesome!
The atmosphere, scenery and art are unique! At the start I forgot it was kinda of a horror game, but the first jump scare reminded me that XD
There are pretty good puzzles and the story is intriging, I really wish I was playing the full game. I'm curious about how the boss fight will be!
Now I have some sugestions.
At the Yurei segment, there are the boxes you have to push. In the game you can push and pull boxes, but for some reason, I can't pull the boxes in this part. It took me a lot of tries to do that, but then I saw that I had to just push the boxes to the corners. But I think it would be interesting to make the boxes pullable.
Another thing is the clown balloon segment. You have to go forward the exactly moment the clow says "next". It took me more than 10 tries to get past this part... I think it's just me, but I would recomend having a tolerance of at least 1 second to the player hit the forward button.
And the checkpoints. This game is hard, and you'll die some times until you manage to do what have to be done. But there were parts that was too long to get to the dying part. Like the ferris wheel segment, where every time I died, I had to go up again, when the checkpoint could be already up there. Or the Yurei segment, where I had to push all the boxes and go up again for another try.
In the overall, this game is great, beautiful and very interesting! I look forward for another updates or the full game! I'll definitly buy and play it! ^^
Keep up the good work, and congrats for making this incredible game!
