Once I got a hand of the drawing I really loved the gameplay. I would create floors as I ran across the room like it was a magic carpet and felt great. Moving the balls with the lines can feel a little tedious but it adds to the difficulty of it and wasnt a massive detractor for me.
The art style is really cute, loved the simple character spikes and doors. If it weren't from the description I would have been really confused by the sudden game over screen when I took too long to complete the game, maybe some ingame timer or hourglass could have been good, just some indication that my time is limited or coming to an end.
I got faster with every attempt and certainly could see this expanded on and polished.
