Haha, It is quite a good song. We actually just released our game on steam! You can also buy the DLC that includes all the sound tracks found in the game if that is something that interests you. Glad you like the song and happy slaying!
To get the hard badge you have to be able to fly over the boxes. 1st day buy max transmission, engine, wheels, and spend the rest on fuel. 2nd day buy gun and as much ammo as you can. 3rd day buy boost and as much boost fuel as you can - use the boost on the very last hill to fly over the boxes and get the hard badge! ++ because it works!
Flood the screen with scouts and you will win almost every time. You can send several scouts to the other side before the enemy even gets one unit to your side. Try to make sure they don't actually have to attack. If they do, they die.
Why is it not possible to upgrade the cooldown for the cannon and other weapons where you click? That would make this game so much less frustrating, especially because we don't have many points to work with.
I thought this game was awesome until I realized how often the penguins get stuck. There should at least be a way to make them attack a different target, or at least temporarily control them so they don't walk face-first into the wall until they die... developer's response to this problem is quite lame.
I had given this game 4/5 until I started playing boss battles... they were so frustrating that it just killed the fun for me. One mistake and you completely die! What a stupid game.
That is on my list :) hope to find time for it at some time
