This was amazingly well crafted for just a month of work! The story flowed nicely, and art was really nice, and the music fit nicely, and the puzzles. I really enjoyed all the puzzles. They felt a little escape-roomy/old-school-adventure-game-esque with the cool connections between various pieces to find the combinations to unlock things. The zombies were also a scary surprise, and very cool when the lights went out and the music changed and you are panic lighting the lantern.
If you have plans to go over the game and polish it a bit more: The UI could definitely use some enhancements, somehow highlighting interactive objects would be nice (I found the matches and the key in the fountain completely by accident, just sort of randomly click around), and knowing what item was selected in the inventory would be helpful. Also clearer indicators of locations (I didn't realize you could walk into the first door in the clinic area until I had literally gone around the entire place and interacted with everything else). And a little AI to make the zombies a little more interactive to dodge (like make them pause a second when they get close and then make them quickly move to the player's location when they paused).
Overall though, amazing job for a month of work! Story was nice, and sitting through and reading the journal at the clinic was great. The parting picture of the flower as Aster is escaping was great as well. And the puzzles, once again were all really nice (especially the safe combination one! Would love to see what other games y'all can come up with.
