I completed around 3–4 levels and wanted to keep playing, but I felt like I was fighting against the controls rather than solving the puzzles.
To improve this, I would switch to a grid-based movement system. It would make navigation feel more precise/juicy, simplify future level design, and open up access to many puzzle-generation algorithms commonly used in this genre.
I think there should be a keybinding to control or interact with the car(Space), instead of UI button.
For your free player movement, you could add objectives or some fun interactions with objects. For example, the player needs to collect three toys for a cat (or complete some sort of exploration-based task) before he can finish the level.
