I think its a good idea and the theme is very well implemented but like other users have alredy told you, it has a very big difficulty gap, which doesn't mean that it's a bad thing, but making hard levels could make potencial players quit. However, the audio was excellent and overall a good game to play. I would recommend explaining in game or in the first level how the ability works because I was lost for a few seconds.
If you wanna check out my game submission, you will see how my levels are easy, to make sure the players enjoy the game overall.
