Beat the game.
Taking a cube and morphing it into a target pattern is fun! It reminds me of a game I played when I was a kid in Thinkin' Things collection 3, where you had a bunch of aliens that had to change a picture in a specific pattern to match the same picture but already distorted.
The initial puzzles were nice since you could see all the patterns at once and think about how to fit them together, the ones that had a pattern that changed a lot were hard to follow (both the sequencer and the randomizer). The sequencer is specially hard to handle, you have to remember all the patterns and you can change them whenever you want. I can imagine people having a difficulties with them. I ended up just adding patterns together and hoping I was not using an incorrect one.
I know this is more a proof of concept more than anything, but handling the cube felt cumbersome. When going from puzzle to puzzle, putting the cube in the goal slot, taking it out and droping it on the middle of the next chamber's floor so I could see what was new got a bit tedious. New cubes could be present for each room.
And this is something dumb, but after reaching the top and finding out I could walk on top of the walls, I tried to find a hidden puzzle outside the rooms. Found a floating rune at least!
