The aesthetic is great and the gunbunny character design really makes a huge difference somehow. It feels right (in the controls, left + right = shooting ears, also the hop), it makes me feel more attached to the lil critter (so the protective shooting power feels even more satisfying), and it makes me invent some narrative while I play (e.g. poor bunny test subject, doomed product of military research science, trapped in unlit infinite razor barrel, each movement monitored only by AI and ultimately boiled down to long-decimal numbers spattered over a spreadsheet on a clipboard that someone will spill coffee on when the "top brass" barges in etc. etc.).
The charge-up time before shooting feels good too.
