Really love the game! I really like how sound and text are used to hint at the player's location. Also, the way you interpret the theme is also quite interesting.
However, due to the isometric perspective (not fully top-down), I found the directional controls a bit confusing. For example, at first, I wasn't sure if pressing "D" would move me to the right of the screen or if the movement was based on the cat's perspective.
After activating the radar, I was also unsure of my exact position. Perhaps the game could display the player's location on the map (like the arrow at the beginning), but movement would be disabled until the radar disappears.
Overall, well done and hope it can expand into a larger game!
