I can totally see this game coming out as a party game (after polish). The 2.5D aspect makes it fun to look at and I love the icy controls. I assume you made the sound effects yourself and it makes the game pretty funny. Some improvements for hitting range and performance would make the game way better. Also the sprites sometimes clips through the walls but those are easily fixable.
If you add some variety to the gameplay (new gamemodes, level modifiers, local and online multiplayer) and polish, I can totally see it being on Steam and having sales. Great game :)
