This game highly resembles Strike Force S.T.G in the arcade. Berzerk Studios, is it that this game is inspired by Strike Force S.T.G? This game also brings me back to 1943: The Battle of Midway. You guys hardcore shooter fans? I think so!
Full Screen mode shouldn't be a webpage on a separate site. It should be a simple flash-window expansion to fit the screen. Or submit the larger flash game.
Add a sound effect for when a foe does. A "Oorah!" or "Gu-nooo!" would be very nice. Add a "Clang!" sound effect for hits by melee units. Add a "Fhooh!" sound effect for bowsmen. Make it sound like a battle! The game's good, and by that I mean great, but you've got to add to the setting.
Make it so that the spoils automatically move to your inventory. Not just in a sequel, or in Sunny 2. In this game. It's so awesome the only thing that's sorry about it is the fact that people like me forget to pick up weapons off of the enemy. Automatic would do that.
I think that having to switch items all the time is pathetic. I enjoyed Infectionator World Domination and this game seems to not quite match up to it in fun as a result of having to switch items all the time. I should have thought twice before buying premium content for this game...
You really should implement automatic saving to a Kongregate account. I just cleaned out my computer and I've lost over two weeks' work, as well as a victory against Villalobos, an ultra-rare tower and many gold generators. Please implement Kongregate account auto-backup.
This game was worthy enough to warrant purchasing premium content. I thought I'd never do that again after my mistakes with BTD4. But with this game it's no mistake. You've done a supreme job on this ultimate flash tower defense game!
Only the last level was worthy enough of testing a gamer's thought processes. You bring great shame upon my desktop! (I'm just kidding.) Visually and pace-wise very well done. It's obvious this game was made to be flashy from the beginning (no pun intended.)
I suggest that in the formation editor a player be allowed to view a list of what units are on the field. I'm constantly asking myself "Where's my Fion Drones?" and "Where's my Vira Savior?" I'm currently asking myself whether my Vira Savior has been destroyed. I think it has... but that's after wasting 4 minutes trying to find it. Implementing a "List Units" command will help tremendously.
I'm glad that you've allowed text saves. I'm tired of my computer "accidentally" deleting my game saves. So I'm saving them to low-space text files. Thanks for making that system.
