The short and simple of this game is that its the same as all the other bad renpy games out there that all do the same thing terribly, which is to say make the entire game about the grind and nothing else. Just mashing through the same task over and over until you get the required amount of money or stat to move on to the next task, which is the exact same thing but "harder."
The long of it is this. This game, along with many others, chooses to have the player do the same task a million times to get enough money to buy an item to unlock a new route that needs you to do the same task over and over again to grind money/relationship/stats/whatever fucking currency or statistic they want you to grind. A vast majority of the game is playing it on skip and going to fight bots over and over again for money to buy something to get to the next step, it depends on the character and what they're asking for. Other than that everything else is pretty hit or miss. The art is fine but it's nothing special since its Ai generated. It's still good though, which is nice.
Honestly I wish people would stop giving these types of games a free pass because of the content or simplicity. The writing itself is weak, the gameplay is weak, the cg is just generally acceptable, and other than being sonic themed there really isn't much going for it. There is no depth or substance at all when it comes to this game with no real clear direction. It's all just wasted time for no reward and some porn crumb trails along the way to keep you following it.
