[FE] More Animations

[michaelhyi]

Description

Frontend engineers should implement some minor animations on the frontend.

Acceptance Criteria

• Additional animations should help make the game feel more alive, more engaging
• Ideally, we utilize CSS animations / SVG animations or any animation library (like framer). .gif files, like we have implemented in the past, is unfortunately not considered the best practice (realizing this after Sujal's ticket, sorry!). But for now, if we want to use .gif for simplicity, that's fine, since animations are rather simple and pixelated.
• Sujal had some ideas, like shooting stars in the backgrounds. Come up with new animations throughout the application that would help make the game more engaging
