Why does every multiplayer game on kong have a stupid energy or stamina system that is only refilled by time or buying something with kreds. It's bullshit.
Seriously need to put more thought in the controls. Why would you bind the controls to dominantly one hand that isn't the standard WASD for movement and a key on the right hand side of the keyboard, the spacebar, or left clicking for the shooting or anything previously mentioned besides the left click for the bomb?
Once you unlock a tower type, it should be permanently unlocked so you can use it on earlier levels instead of that level and on, but everything else is perfect.
If you just want the badges, quickly get to the sky by a launcher and spin and flip to the clouds, there are a lot more multiplier gems up there and when you get superman mode, kill a bog fly, you get A LOT of points.
