I wouldn't exactly call this a bug but on my like 5th save file, sometimes bunnies will just vanish off the screen or will fly off like they've been shot when I never even shoot at them...This doesn't happen much but I just thought it was interesting.
First off, great and original game. The levels have decently advancing difficulty (except for the boss, you can just farm the levels for cash to get all the upgrades). AS for the targeting system, yes it's very hard to use, I always strafe though so it doesn't matter. Great game overall, just almost no replay value.
As a side note, the 150K achievement badge should be impossible not hard...
Really great game! Best defense game I've ever played, definitely a 5/5 star rating. Although it didn't register me beating the queen...BTW I beat the queen in like 5 seconds I just bought 20 of each grenade and spammed the A and S keys while firing my minigun.
