Clever gameplay - I liked the button prompts that came up occasionally to interrupt the otherwise simple gameplay.

The game is pretty simple and fun. It also realizes the theme pretty well. Though it could use some kind of a small punishment for pressing the wrong button when a block pops up. Apart from that its a solid game.

Simple and neat! Definitely got caught off guard with the button switching! nice job!

simple, clean and tricky - well done! I like that you have to use different keys to fix the cycle
