Hi Vultwo.
Personally I was expecting a more 'visual' game. This looks more.. I don't know, text based? I always prefer to see some sort of 'world' in which it all happens. Heck, it would even be fun to see a vault increasingly being filled with stacks of bills! (A là Payday 2) Could be same for the goods.
Anyway, you could improve the looks further. Currently - that's just my opinion - it doesn't look uniform. For instance, the graphics of each drug are pixelated, and a bit smoothed. And your actual text; is always smoothed. To make everything uniform, you should choose either a total pixel style or smooth style. (I'd recommend the latter)
Shouldn't it be spelled 'illegal' by the way?
Now I may only look at visuals (that's just my thing) and I know it's hard to make things, especially UIs look good, but you might still want to improve it even further. I mean, you got those outer borders, transparency, outer glows, it could still all be improved to look more clear and professional.
The second screenshot you posted '-10 health' now that looks better than the other two. You didn't use any borders on the text, and the backgrounds made sure you were able to use one solid simple fill color. Of course it's got less going on on the screen so it looks a lot more clear, but there you did it better.
You can always look for samples of UIs on Google images or Pinterest.
Also regarding the Apple guidelines, well, it IS a game about drug dealing so I can totally understand why they didn't approve the game. I don't know Google (Play) their policy, but I *think* they will have a similar policy.
I think to get approved you could use 'code names' for each drug (e.g. 'Blue Magic' - winks at a certain movie), and make sure you avoid the word 'drug' and 'dealing' in the first place. Perhaps use something along the way of 'goods' or 'commodities' and 'trading'. So that you know, everyone KNOWS what it is, and what the game is about, but you don't say it literally. Replace the word on the second item of the first screenshot also.
Say.. 'hustle' isn't that more of a term used to you know.. sorta beg for money? I'm not sure though. Just trying to put 1 and 1 together (the name of the game and the game itself).
