Enjoyable, but there needs to be some kind of incentive for using more than one element at a time. As it stands, when I have 224 essence elements for dark and that's my highest element bonus, I'd be losing out if I did anything other than fill the screen with dark spells.
Eh... Your "fail safe button" is more of a "fail button"... If you keep clicking it while a wave of enemies is attacking you, they won't fire at all because they're searching for a new path.
Need to fix the damn turrets. LITERALLY been sitting here 20-30 mins now trying to take the only base i can get to but a SINGLE TURRET is killing all my beetles before they reach it.
This game should work perfect is you don't have any problem with internet.
