Fun little 8 bit romp. Difficulty sadly, is probably just a little too high. If you were aiming for hardcore gamers, fine - but right now I couldn't bring myself to try and go past Stage 2.
I had three of those red explosive monsters come up to my barricades in a line, and BAM - four soldiers down and all barricades blown to pieces. I truly felt like there was NOTHING I could have done, or feel inclined to do, to attempt another set of waves just to get nuked.
If I could retry a wave instead starting from the beginning all over, I could possibly try to best a wave again, but right now, I feel the game is unbalanced.
The droid is a nice idea to have some first hand control inside a defence style game, but the offensive capabilities, even when set to the offensive droid setting felt weak and unhelpful.
Everything else is great! Love the soundtrack, animations are simple but do what's needed for this style of game. Tweak the difficulty or offer more upgrades to balance the game-play and it's a winner. Right now, I won't be coming back to play again, but only because of the game play balance.
