Fun little addictive game that uses its main mechanic really good. Really good job, but still could use sime minor additions. Current control scheme fits the theme of the game well, but it can be quite tricky to aim (maybe an alternative control scheme where the charcter moves towards you mouse when you leftclick?) and maybe some enemies that would move in a different pattern towards the player, so you can't just stack them all in one giant pile and then basically massacre them.
But overall, really fun to play, good job!
