Your game design skills really shine in this game. You slowly introduce new mechanics in clever ways with hints to help. The difficulty is very well balanced with incredible levels. Usually in games like this, I find myself getting frustrated. However, this one just felt like a challenge and really made me think.
I REALLY liked how you made it so you could not cheese the levels by standing still for a long time to make the shadows stand still later.
The game is super polished. The graphics are amazing. The way you credit the songs in the bottom left as they start playing is nice. The controls were perfect with no complaints at all.
I have no feedback for you. This is a perfect Jam Game in my eyes. Well done!
