I tend to have a bias against RPGMaker games, but I enjoyed this one. I like how you added the puzzles, and how they differed from each other. I also liked that puzzle pieces didn't auto lock, and you didn't have to lock the pieces into place to "solve" it, instead solving it in a more realistic way. The other characters solving puzzles was a nice touch as it made them feel "alive." One of the puzzles requires knowing Japanese numbers, which I loved because I got to use my languages knowledge in the wild, but I'm not sure how others were meant to solve it.
I appreciated the inclusion of checkpoints, though it should be made clearer that the animals are the checkpoints. The chase sequences suffered from the same problem as most other RPGMaker horror games. They're a bit glitchy, and there's no room for mistakes. They do add panic and anxiety, but when they're this difficult, they start causing frustration more than anything. The transition of moving the stool to under the ladder was a little bit confusing, and could benefit from some sort of dialogue. Also, puzzles still sparkled even though you could no longer interact with them.
The game had a good creepy atmosphere, though the music was a little repetitive. The game itself really felt like a waking nightmare. The events in the game were terrifying, and they continued to happen with no hope in sight, causing feelings of dread and despair. The writing could use some proofreading, and some word choices seemed strange, but for the most part, the story was good and kept my attention. However, the ending sort of fell flat. There were a lot of unanswered questions, and there wasn't enough information given for the player to fully understand the story.
