I adore the controls on this game. I understand you were on a time crunch for this game which is why it feels a bit incomplete. That being said, if you do plan to any more with this project, aside of the obvious stuff, I highly recommend unique interactions with the cart, like a potential lose condition being flipping the cart over. (I noticed the cart can rotate a bit off axis, and then corrects itself - but what if it didn't?)
Also, those cutscenes with the microphones. what in the world are you recording on? Because the audio quality of the audio is smooth.
