This was a pretty cozy, no-stakes run you provided here. The black-n-white outlined style lends into a cozy stormy night whilst still making items identifiable as lights or platforms. I also like the subtle level layout that entails what can be jumped on and from where, really taking advantage of the appeal of curiosity and experimentation of low-stakes gameplay.
There are two things that irk me when playing, though. One is that the jumping controls can feel clunky. The jump is static, and the pounce sometimes doesn't given enough horizontal control for platforming. You can probably keep the horizontal controls for cat-like platforming, but the lack of adjusting jump height feels jarring. The second is that the platforms are hard to distinguish the background elements from the interactive elements. There's no rim lighting on the top of platforms that distinguish those areas from decorations.
