I've only got into top 10% today, about 210 floors. Really enjoying the game. Definitely not pay to win havent put a dime on, and the game rewards you gems the premium currency in the game after floor 100 threw out your battles. It is an idle game so you do gain normal in game currency you can grab from shop. Also the game has weekly rewards that are more than fair. Only problem is I would like more content, theres no way of communicating with the community guilds would be a nice integration.
