nice game! I like how there is a mix between idling and placing the cannon in the right angle. Achievements are also nice, especially that you get research points for them. 5/5!
i experienced a glitch in defense mode: if you move the gun to the right edge of the screen and shoot the game glitches up and everything stops working
Nice work! The weapons' behaviour is pretty realistic. There is one problem in defense mode: When you hit the box containing the missiles, the bullets fall to the ground and after a while this gets extremely laggy, especially with fire bullets. But altogether, it's a very fun game - 5/5!
