The builds have now been updated.
Aside from the bug fixes and additions mentioned in the post yesterday, this is also included:
Addition of sequence of hexes turning on and off at the beginning and end of the game respectively making the use of them more intuitive for beginners.
Corrected bug where airstrike costed nothing on first use.
Corrected bug where bugzapper costed credits regardless of whether it hit an enemy or not.

Known issues in this build include:
Fire sound for ants is temporary and sometimes plays too long.
Sound of turrets when aiming for mosquitos repeats too often.
Selected enemy will not revert to normal color when killed.

And other minor issues.
