Your game is so adorably designed! The simplicity allowed me to enjoy the gameplay without being bogged down by any confusion. I agree with previous comments that some kind of border or wall to know my "limits" would help.
I'm wondering if you were to develop the game, what different levels might look like or if you could create a narrative to the story! I also think that the game's visuals are charming, and you could work on the game's UI to be just as "handcrafted" and appealing.
