Thoroughly enjoyed it. The puzzles were very good. I'd say the combat is too easy. The zombies never posed any threat. The game could also really do with a map and to rearrange the rooms into a more logical pattern. Currently it feels too maze like. I'm sure it'll be a lot better if you can differentiate the rooms with different textures. I'd also say the intro cutscene is too long and I forgot I was playing a survival horror game and not a visual novel. Also, try making the vn text be locked in place rather than shifting around, because its very hard to read. Overall good job, I'll happily play future updates.
