Great!
I agree we need more upgrades and definitely a faster recharge rate, or at least allow the battery to become full after we beat a level. Its frustrating using all of the power during a level to only be left with almost nothing for the next, harder level. I like how the enemies become bigger though. Very fun game.
Great start, try expanding!
Needs to be a little more challenging.
pretty good
needs more upgrades=D
Not really historically accurate...
But still fun. Just a little background: Nickolas Tesla was Croatian, which, at the time of WWI, was a part of Austria, which was Germany's ally. Besides, Tesla was a U.S. citizen long before WWI started and died before the end of WWII. But the game still entertained me, so I guess its not really a big deal.
And also, @ Narhethi, You do know the game ends after day 20, right?
20 is ridiculous
I honestly think that this level is almost impossible, but also that levels after this (if there are any) would be even more impossible?
Good game though.
