Nice, short little game. And the story is cute. I have a few criticisms though.
The controls can feel way too heavy or slippery in certain parts. IN the first area, it was too easy to bonk against the ceiling and hard to get to one of the levers. Floating platforms in general in the first area were hard to land on. Maybe it is because the mouse’s hitbox isn’t obvious.
In the first area, it isn’t really obvious where to go because everywhere looks the same and the stage seems to go in every direction. On top of that, it’s not obvious when a switch is in an “on” or “off” position so it is hard to tell at a glance if I have already activated a switch or not. And it is not clear which switch interacts with which door. Thankfully these issues only affect the first stage.
When I mentioned controls feeling slippery, the elevator section is a good example. The first time I was there, I slipped off of the elevator and wasted a lot of time trying to get back up.
