So this isn't just your game, I've noticed it a few times on other games with mouse only controls, but I'll mention it here so hopefully it helps you and others (and I need to check my own game!), I struggled with the touchpad on my Macbook Air. I never seemed to struggle with a mouse, but it was a little wonky using just my laptop.
Outside of that, this was a fun experience and interesting design. I would have preferred if the camera was either 20 percent closer, or the sprites were larger. I want to see the little animations and interactions, it would keep me more engaged in the moment-to-moment gameplay.
Overall, an ambitious effort for a solo dev in a jam. I'm glad I spent some time with it. Great work. You should be proud.
