Overall, the game is great. I didn’t encounter any bugs. I really liked the music and the dialogues. However, I did miss some environmental details. Sure, it’s a maze, but maybe adding some paintings or decorations could make it feel more lively.
Another thing is that I wasn’t really sure what the goal of the game was after talking to two zombies. A short explanation about the story or the objective would make it clearer.
The controls were excellent — I had no issues with them at all.
Overall, a great game, but adding a bit more environmental detail would make it even better.
Suggestion:
To make it even more interesting, if you have a bad dialogue with a zombie, they could become aggressive and start chasing you. If you make friends, they could give you an item or help you in some way.
