Really cool! Simplistic visuals are just so simple (which is great), and yet they convey so much at the same time. The levels are challenging yet completable, which is a perfect balance imo- one thing to maybe think about is just cutting down on the number of levels. I know it's easy to just make and make levels, but 20 feels like a bit much to play to be honest. That being said, this is another top 3 game for me! Really really well done!
