Metatanks version 0.9.4 is out! This version is mostly about two things: making the game more user friendly and nice looking, and making the enemies smarter.

Official changelog:

Gameplay Additions:
-Added particle effect for enemies surviving a shot.
-Added a better particle effect for the Metatank destroying projectiles when it goes into its third phase.
-Added a particle effect for the Metatank's short lived forcefield in it's third phase.
-Added a particle effect for a bunker getting shielded by a shield bunker.
-Added effects for things bouncing off of walls.
-Added effects for the Charger hitting a wall.
-Chargers can now run into each other.
-Added a temporary menu soundtrack.
-Added a trail to shells that will bounce off of walls.

Gameplay Changes:
-Slightly optimized the shield bunker's code.
-Slightly optimized some code with shells.
-Overhauled most of the ais in the game so they aren't outlandishly dumb. Now they are just very dumb.
--Tanks now try a fair bit harder to get around walls.
--Enemies check in a small, vaguely cone shaped area in front of them their friends, so they are less likely take dumb shots at their friends.
-Improved the reload time of the Missile powerup and Machinegun powerup.

Bugfixes:
-Fixed issue where the wrong variable was being reset when an enemy's target doesn't exit. I honestly I have no idea if this actually changed anything, but there you go.
-Fixed minor visual glitch where the effect for a bunker losing it's shield from a shield bunker didn't work.
-Fixed a bug that was actually caused by the previously mentioned Shield Bunker's optimization that would cause bunkers to become invincible if they were moved out of the range of the shield bunker(s) protecting them before the bunker was destroyed.
--That's the longest bug fix text yet. huh.
-Added some code that was missing from the Metatank's shells that prevented them from bouncing. How did I miss that one?
-Chargers should be less likely to get stuck in walls. Should. They also shouldn't have been able to before but here we are.
-Fixed bug where turning on music wouldn't play the menu theme until a level was entered. This couldn't have come up before this update since there wasn't a menu theme before now, but it's still important.

Other:
-Added a screenshot function as a developer tool.
-Added a button to delete your highscores.
-Added some people to credits.

And:
-Probably more that I forgot to document.
