This game was really pretty! You nailed the look. Very unique design, clever take on the theme, and it's memorable!
It was just frustratingly hard to get the rats to do what I wanted instead of run into a corner to get stuck and not chase anything that I telekinesis for them.
I've attempted a similar idea game with directing 60,000 cats (litterally, haha get it?) around with a laser pointer, but the cats could want to do something else, like chase a ball, or sleep, or get in a cat fight, or some other other cat things. I was never able to find a flow that felt -good- to play. Your game felt to suffer a lot of the same gameplay flaws that mine did.
If you happen to explore more with this kind of a gameplay concept, please let me know the outcomes of those attempts!
