Same as ApeHardware.
It felt a bit slow at the beginning, since it was mostly testing the mechanic with nothing happening.
It's a bit too much of a slow burn for my taste.
Thought, it was enjoyable to play.
I liked the framing device, and how it unfolded, even though the direction it was going was a bit obvious.
It was also nice to have an option to remove the VHS filter, which I found to be a bit strong, so the option made the game more enjoyable to me.
The only thing I really didn't like was the sound.
Notably the sound when you move the telescope around, which I found very grating.
Overall, nice experience, told in a cool way.
