The concept is very good, but the game has an imperfection:
It could be just me, but I feel like my decisions barely matter. Whichever dice I choose, the outcome is more of a matter of luck than decision making. I think a quick fix to that would be increasing some dice's average and price, while lowering others', so you can decide to go safe and earn less or risk more and earn more. In this state, the luck stat is pointless, because whatever I do, it does not feel like it matters, but if done right this mechanic could be great. Same goes with the costumer happiness, I feel like I can't influence it in a meaningful way, no matter how hard I try.
Other than that, the game has a really good concept, and good potential. It looks good, the sounds good, although I think some music could greatly improve it. I also liked Felix's character.
