Ok this a good game
The only thing i wished was diferent in a game design perspective is that you usually use click to play but when you want to replay you have to press space bar so it is kind of unconfortable changing keys, when you just want fast addictive replay!
Besides from that I think that movement or maybe the animation could be improved a little bit, sometimes it feels as the click is not so responsive
I think you managed an adictive gameplay and a nice theme so congratulations nice game!
