A little problematic.

The plot is not bad and so is the animation.The aiming is a problem as even if the power bar(not at the bottom but at the front of the cannon) reaches its limit,the shot does not reach far but it needs to be held on longer to shoot further,so the power bar needs to be more accurate in determining the distance of the shot.The characters need to move faster or have an upgrade for that and the skills need descriptions in order for everyone to know how they work and maybe the penguins could have weapons different from the enemy,so the same weapon will not end up being used repeatedly by both sides.There should be an indicator to where the shot might land like a curving line which pin points on a location so as to make the shots more accurate and maybe even the number of enemies and the penguins.
