The mechanic of using the numbers as platforms was quite neat! However I only felt the need to use just the number 1, plus it did glitch out on me at the last level forcing me to use number 1 when I found a legit use for the number 3, despite how little levels there were each level was pretty long and felt it used the mechanics introduced well, the color palate was a nice choice. this pretty good, it was easy but made me think. (Also I found your little C key cheat code ;3)
