For improvements:
-Knowing how long for h-scene to reach climax.
-The plant vs zombie gameplay is weirdly difficult but lacking other slimes. And its UI was hard to learn at first.

Good potential however it took over 8 hours of AFK to get everything so speeding up the cookie production should be a priority to improve the flow of the gameplay. Adding as others have mention an upgrade to speed this up will greatly improve the game overall. As the money does not contribute much after the first hour as everything is easily bought in a couple of minutes.

I like how you captured the feel of the song but in sections like at 1:50 the bass overpowers the melody. I wished the bass was a bit more muted during those sections so that the melody can come out more.

I simply love it.

I like the beat but I was expecting for the beat to go faster.
