WOW. I really like the gameplay mechanics, it's super fun and engaging. I can play this for hours xD, The core gameplay feels really solid and addictive
The only problem are the visual and sound. For it, first you can try to create a visual style guide on how your assets can match the story theme and how can it be engaging + blend so well with the theme. You can also try to sketch all the asset first and try to mix and match every asset's style so it can balanced each other and boosting your visuals++.
But seriously, the core gameplay is super solid and fun, just need improvement in the looks! Looking forward to the next update!
