The atmosphere, the graphics, the zombie combat, man it was all really well done! I have to say the progression felt very natural, finding the keys was intuitive to me, I just had a feeling were the next one would be. The mechanics were solid and responsive, the audio was excellent and atmospheric.
The only thing I found a bit tedious was the zombie fights near the end, it felt like they were being thrown in just to make it more difficult but it made it feel like it was unnatural if that makes sense, also a bit of variation in the zombies would have helped, maybe some little ones that are fast and a boss one that is just a tad bigger with red eyes and more health would have made a big difference.
The end was also a little anticlimactic I was expecting some kind of eldritch horror by the end but overall great job everyone, it was a fantastic and polished experience, one of my faves!
I share this critique because I loved the game so much, and as a dev I always feel a bit constructive criticism pushes my games even further.
