Great concept and decent execution, the gameplay loop is fun enough although a little repetitive, like others commented more options and content will only make this game (or another similar one project) much better.
The RNG is good enough and dying doesn't feel that bad since progressing is fast and the random encounters keep the experience fresh for at least 4-6 playtroughs depending on how long you can last.
Lastly, I can appreciate this fresh take on a zombie apocalypse game and hope to see more of it in the future, very creative use of the RPGmaker engine.
Keep up the good work!
