Hi..
Enjoyed the game. The design was simple and the idea was really good. I was gonna mention that audio could be one of the things which would have made this game more immersive, but I went through the comments and turns out the audio bugged out. Well, nothing much you can do about it at this point in time.
I had one more observation. Since in the game player doesn't know about when actually the trap is gonna pop up, you could increase the control the player has on the character by adding things like 'Jump Buffer' and 'Coyote time'
