I'll start off by saying, wow. What a blast from the past. The characters (I believe) are from an artist who started out years ago. At the least, it feels like I first started seeing their work about 10 or so years ago. Can't remember their name or a single title of even 1 comic/short picture stories. But it was this type of art style that really drew me into vore.
That all being said. This game is overall decent, an excellent way to kill some time if you're into strategy. Graphics are debatable. Obviously, the characters look the best out of everything and that's honestly what matters most to me. It's especially nice to see them in a 3D-ish kind of style.
As for the gameplay, well, it's certainly hit or miss. Despite being a strategy/defense like game. Honestly it feels as if there is only 1 strat to do in this game. Which is buffing your cheap fairy girl before starting a run. Try to place nothing but them until your forced to use a naga or deetaur. Until you get the next rank of popularity and hope you get the mana generator naga. Place her down asap and go from there. (Usually I go for placing the mermaid lady who makes spells cheap. Place a minefield of voracious portals around the mana generator and exit. And boom, unless your absolutely flooded with dudes, you get a perfect run everytime.)
Speaking of perfect runs. Honestly it does get a bit annoying the further in you go. It's fine if 1 dude slips past on wave 5 or so and you gotta reset from there. But highly frustrating when it's wave 10+. Seeing as the number of waves jumps up to 20 as well. It can be time consuming. It gets far more annoying when it's only for 1 extra star and the stage is one of the boss introduction stages. Having to wait an extra 10 seconds just to watch a dude throw on a shield. Repeatedly. Not exactly the greatest. But that's probably the worst thing this game has going for it. Everything else is just a matter of tolerance and skill.
