~Entertaining game. Several combo powerups I found were: Yellow Laser+Double Fire, Ion Wave+Tetra Shot and Ultra Fire+Double Missile Blast. It does get annoying when you accidentally pick up another powerup and kill your epic combo.
This has pretty good maps and a turret idea like Antbuster. Heck, the map idea makes this game unique, I rarely see any tower defense games that have walls that make you think about your tower positioning. And the Megatowers, ef yeah. Do I see DTD doing any of those things? No, so this is not a ripoff of DTD.
Nice selection of music. It's that mix of music and danmaku/bullet hell/curtain fire SHMUPs that really make a piece of art. I can see little bits of Fraxy influence, nice job.
~Pretty fun. Just like Last Stand, but a top-down version of it, plus ammo limitations. Kinda annoyed that I lost in the first round because I found no survivors and very little assault rifle ammo.
