Originally at the start, I wanted to avoid puzzle platformers as I thought that it would be the most common and that there would be nothing I can do to make a unique puzzle platformer. Well, you're game definitely proved me wrong. Aside from the main mechanic, there were certain moments in the game that really struck me as genius. Two in particular is when you link a key to a box to get more keys, and the other was when you actually had to avoid collecting keys to go across a bridge of gates, so you use a moving gear to move the key away. All in all, You've made what I thought would be a common and generic genre for this jam into a unique take on a solid mechanic. Well done!
