The game is actually very interesting but mechanics and level design did not match up.
In your actual solution video solutions feels they are more like a speed run hack.
Also showing colors order in game play would be good so we can know which color is making things longer/higher than the other.

I understand what you're saying, and especially for these early levels there should be designs where you don't need to use the run button to complete the puzzle - but then, later levels that require the run button will be much more confusing due to never introducing the mechanic, and at that point we should just cut the function out entirely.
