That's a pretty neat idea, that fits the theme very well, 

Think blocker hitbox truly is a bit too big probably, and the music could get a bit monotonous after a while, but if you choose to move the blocker, the gameplay is pretty fun!

A nice, simple and short game.

fun and good game 

really cool idea and making the slider accelerate really fast was gold, it really increased the difficulty of an otherwise dull game. Nice short experience overall.

decent idea, when the game begins u can stay in place without moving in the start position for a minute before things can get around you, the blocker is also way to uncontrolable
