Admittedly, the difficulty ramped up pretty quickly. If you were to give it a second shot, there are three levels in total. In the last one(with the laser walls), the first cube is part of the solution. I'm pretty often in one of the voice chats in the Discord, so I can help you if you want. If I'm not there, someone named Peanuts is also often in the Discord's voice chats and knows the game quite well and could help you if you'd like. Anyway, have fun with the jam!
