Huygens Principle is a retrowave 2d top-down shooter with body swapping. I started this project in February 2016 and now it's done. It took longer than I thought to make 169 levels and all other things. This game is hard but I tried to make it as balanced as I could. Game has retrowave/synthwave sountrack that contains 16 tracks that I like.
