I liked it!
Version: Windows 4.1
Graphics, game feel, puzzle elements and the euphoric solution moments were awesome and I can't wait for more!
Some feedback:
Going Up: It wasn't very clear what was going on with the different colors. After completing the demo, I understand the difference between the object and "platform" polarity colors, but at the time it was confusing seeing the 3 different lever colors not match up with the color of the platforms.
Hold This: Maybe I was just dumb because I can't recreate it, but I couldn't figure out how to jump off at the top of the pully. I also don't fully understand the difference between the doors and the pipes as goals.
It Takes Two: I loved this level, but it felt like a bit of a difficulty jump. Probably fine as it wasn't too challenging.
(Forget the name, before Middle of the Road): Wish there was a little more time between the platforms to flip the switch
Above All: This was by far the toughest stage. I assume my solution was correct as I couldn't figure out another one, but having to quickly grab the magnet as it travelled up on the block, then throw the magnet to the other platform was not obvious to me at all. The fact that it was a bit tedious to restart the level made it more of a slog than fun.
It Takes Three (Part 1): Great introduction to the polarity mechanic, but I'm not sure the F key is the best one since later on it becomes difficult to fluidly move and change polarity at the same time.
It Takes Three (Part 2): I'm almost certain my solution was incorrect since it didn't use the button, but I basically floated over by swapping polarities. Also feel like the lock and key would feel better if the lock explosion happened when I touched the lock.
Parabolic: This one stumped me for awhile to the point I almost gave up, but not sure it needs to change as it was so satisfying when I figured it out.
Over and Above: Not sure I figured out the correct solution, just found the perfect angle to throw the magnet from the propeller. Couldn't find out any other way to do it.
Look out Below: Great level, 10/10
