Fairly simple linear solution, a bit repetitve if I'm being honest. I've said this before about some of your maps but it especially applies here: you gotta make it easier to differentiate the cubes. Since you have to reset the cube at the end, it's really important which cube you put on the button beneath the funnel and it gets really tedious to constantly have to keep in mind which cube is which when they all look the same. Beemod has an option to color the cubes and if you don't want to do that, you can just make one regular, one companion and one frankencube and it'll get the job done.

Nice one :)

Fun map. Thanks
