Give me ideas for my game features

I’m making a game where players shrink and need to press a button to become normal again. To reach the button, they need two items: a plank and a rope. Players must bring these items to specific spots, and they are automatically placed once delivered so the player can progress.

Here’s how each item’s challenge works, along with some additional ideas to make the gameplay more fun and challenging:

1. Plank (in storage):

• Obstacles:

  • Two fans pushing the player away.
  • Pipes to climb over.

2. Rope (in kitchen):

• Obstacles:

  • Climb a plank.
  • Water drops falling from a pipe that push the player back.

And to go to both the room we need to go through main room which have a cat which will attack us

But it's not good enough I need some idea to improve my game and some machanic to add in my game to make it better thank you
