As it stands today, this game is a 4 star at best (if dev got up and walked away today). I'd say it's a 3.5 star game today, but the only thing holding it back is the amount of content. I know this developer's previous titles have been very well received so I am confident that this game will one day get that content, so I'm rounding up to 4 stars.
There is nothing new to this game, it's a trainer, it has custom art and animation, and it does everything it is doing well. It is a recipe that has been written long ago and it looks like this game is executing well on it. I'm not saying that as a negative, innovation is risky, just letting you know what to expect. If you've played a good trainer, this is that, just very early in development.
