Well this is interesting. I like the characters. The player attack is like "spooking" the enemies away. This could have some more features, new attack or new enemies and traps.

The attack is based on the timing, so it's weird while the character floats in the air while the other physics are more realistic. The world is weird though the characters are very cool: why are these characters living in the dark "boring" castle hallway full of spikes and other deadly traps? Are they living in there, or the player character try to steal/or reach something there, or running away of something? There would be counting scores or something as well.

This game has a lot of potentials to be something really fun. I think with some music and some sound effects, this would be a lot different to play. The visuals are really good though. 

Cute game! It has potential
