Astronaut Pen = Cooldown reduction +30% (33000g)
Radioactive disk = Cooldow +35% + other things (10440)
I can't buy anymore the radioactive disk, good job developer, please fix this
Wow, the tutorials even FORCE you to spend your diamonds on garbage you don't want XD -bad and obvious KR clone, even the names of units are the same -unskippable tutorials that force you to waste resources (even paid for ones) -stamina meter "pay to wait" crap -paywalls at every corner -misleading wording to make the paying players waste their money on accident -"pvp" thrown in just to make it even more appearent how much stronger paying players are -no fast-forward in battle to make you even wait WHILE playing There are no redeeming factors about this game >< By the way, the rules for the contest are deliberately kept very vague and you might not even be eligible to enter, so don't even bother. Rate this game 1 star to let Kongregate know that we won't stand for this kind of crap anymore.
This game is horrible. Full of bugs like enemies getting stuck off screen and you can not complete the level. Boss that do not appear, and I passed the stage 15 when the boss still had 80% health (not sure how), boring, lagging, too few rewards.
