Fine demo.
Really needs them sounds effects next time, them beep boops. I hope you study up on swell audio design.
I know you wanted to game to be fully puzzler, and not have that much movement tech [i cri :( ] but then traversing the levels when you know the solution, especially the level select, takes a while.
I enjoyed 1-6, it was a neat challenge that made you think outside the box, as there was no 'tutorial' teaching about duel magnetic fields.
Wonder what future worlds will hold, I hope they are themed differently, if just tinted a colour.
Perhaps if in the diegetic level select of Worlds' clusters of mechanics could be clumped, and maybe stuff like a little sandbox before trying a level. (maybe even just one optional platforming level, I pray.)
