This is a very great game, short but great. I'd like to see a sequel of it, maybe a little bit longer.
Side note:Entropy alien+Shadow dragon+Shadow dragon+Romeo S = the ultimate team.(made it to level 76 in endless, 450,000$ reward)
Also, for the people who are wondering, the lowest number of rounds you play by the end = the higher romeo you get.
Very nice game, the intro was amazing.Some problems: 1) There should be more vampire boosting equipment. 2)The game rely way too much on the starting grid. 3) There should be a way to leave the battle when you started it. Other than that, very nice game.
