concept of a game I'm idealizing.

Concept of a game I'm idealizing, mixing platform with Hack'n slash. I'm thinking to show the levels that the player passed, and that are comming, on the sides of the screen, generating an expectation. ... I'm imagining a formula to try and keep the expectation and the audience. The game will not have infinite continues, if you die, you need to put a new coin, and is here that I hope to make money.. selling coins, exactly like the old arcades.
