Obviously I lost to the Leprechaun. Ever adding anything to your Slots feels like a loss, since it diminishes your Chances of ever getting 2/3 in a Row. Replacing it, or having the Option to remove Symbols would be needed I think.
The Map also should be more interesting I think, instead of a more or less fully open Area with some Things in between. Picking up Stuff I walk over should be automatic, not require Input, its why I walked on that Tile to begin with after all.
I'd also prefer the Bouncers not be at the Bottom, and just having Time to go around and prepare properly, instead of rushing upwards, but maybe thats just balancing and not on the Mechanic itself.
The Graphics are pretty much as expected, but with proper Presentation and polish this could be a Fun twist on the Deckbuilding Roguelike I guess. Where you don't play Cards out against yourself, but play Slot Machine and other Casino Minigames instead.
