The interface for this game is pretty old school, and by that I mean it reminds me of BYOND before it had any of its cool interface features. If you're looking for glitz you're not going to find it here. But if you're a fan of tower defense games, its worth taking a look since it at least kept me occupied for a while.
I did find it rather aggravating that there are five hardness levels and it went from pathetically easy at level 1 to nearly impossible at level 3. I'm not sure I should even bother with anything higher than that, I couldn't last two rounds at the third level.
I should also warn you about a highly annoying Spungebob reference. You've been warned!!!

Prepare to meet your arrow-filled death, skull things!

Nope, they sure didn't see that one coming...
Well, I was going to post some more screen shots, but as I had accumulated a lot of cash and opted to upgrade all of my unit classes, the game evidently decided that I was cheating and reset my game. Oh well! Let that be a warning to all, spending sprees are bad!
