This was a really great and immersive experience!
The gameplay was original and fun, not too easy and not too hard, really enjoyed it (on the later sections it was much more challenging, but very fair in my opinion). And the graphics and sound contribute in immersing you in the stressful setting perfectly! I also love the old-style graphics, as they are consistent and contribute to the feeling of unease, like replaying an old game who scared you in your childhood.
And I loved the ending.
