Enjoyable game, uses the theme really well. Levels are tough, but not unfair, which is nice. Controls take some getting used to but lead to some interesting gameplay for sure. It is fun to analyze the route you have to take to beat a level (where to put your cursor, when to switch polarity) especially in later levels. Game took me 25 minutes to beat but didn't get boring at all during that time. My only criticism is that sometimes it feels like some mechanics are up to chance, (even if they are not, skill issue on my end probably) most notably when you have to switch states while on a magnet to get a boost repelling you away. For 72 hours, this is a really good game, good job on this.
