I love puzzle games, the tutorilized level are awesome and once it starts ramping up that's where the true beauty lies.
Towards the mid point tho, I figured out the solution or atleast partially solve it by previewing the buttons before pressing space, this was both good and bad imo. It was a good design decision, but it also brings forward the flaws in some levels making them too easy and giving you the opposite feeling at times haha, the levels with a lot of inputs felt the best for me.
Its also amazing that you did all the art and music!
Great job!
