No pause in between levels, the stun from the wind tower is permanent, the range never changes, there's no way to sell towers, the only differences between the enemies are their hp and appearance, and there is no tutorial to let the player know what they are getting into. If this was your first game, it would be totally understandable. However, since I doubt it is your first game, you get half a star. All in all, this requires a massive overhaul.
