Pretty neat overall, I'm surprised you were able to do so much in a month. Having the cable tiles update once a frame is a pretty slick effect, I wish I thought of it. Different conversation responses depending on what form you're in is a nice touch.
1-2 was a slog to collect everything in, you have to do everything in a very specific order and if you mess anything up you have to start over again. Exacerbated by the blind fall or two you need to do in the level.
Nitpicks:- The walking animation would probably look better played at about double speed, Lexy looks like she's sliding.
- The tail being straight down in the rising sprite and straight up in the falling sprite only makes sense if she were jumping straight up and down, maybe just have it lower and raise a bit instead.
- Parallax is a bit wonky, seems to only affect horizontal movement and not vertical.
- On keyboard the movement keys are on the right and the action keys on the left. I know PICO-8 pushes this but generally I think it's a bad setup.
