Glad you enjoyed it! The magnet does have it’s disadvantages sure and I did think about making it only active while you move. However, this is a game jam and not everything needs to be balanced. This game certainly isn’t, even without the magnet. When desinging game jams I’d rather make the game easier and funny than difficult to beat. And if auto farming is what helps you finish the game if you struggled with a level so be it, finish it slow rather than get frustrated about missing that tiny bit of score. Plus with the natural small mice movement it was always possible to farm. The magnet just makes it less time consuming. The ghosts are clearing out mice that have moved into your path after you left. It’s not the strongest upgrade, but I found it fun to include. Had some additional ideas for it, but didn’t get around to implement them.
