That's a cool game. Graphics are very simple, but fine.
The gameplay, however, needed some more work. You only have 3 seconds to react to anything, and if you lose, you go all the way back to the beginning of the game.
You gotta remember that none of us ever played your game before, and thus we don't know what each level look like. When going to a new level, people will try to stop and analyse what does it look like before doing anything... only to get punished by the "3 second time limit" and repeat the entire game all over again.
I think you can make your game a lot more accessible and fun if you remove the time limit and make people only retry the levels they currently failed instead of pushing them back to the start.
