I had trouble with understanding the game at first. But i seemed to figure it out. i think it introduces so many things to the player at once it feels overwhelming.
In my opinion i think the deck size should be reduced a bit. and the mechanics introduced at a smoother pace to ease the player into the gameplay.
I didn't really understand the customer mechanic, the global thing or the coin thing all too well.
I got to the boss and died cause my coins were sucked away by the wine modifier thing. and it feels pretty luck based, or can you actually time the slot machine to get what you want.
I think it would be better with more game events, tiles and a more straight forward gameplay system. of course this is just the Demo so I'm think asking a bit too much.
This is just my experience though so don't take anything too seriously. i don't really play deck builders all that much. A pretty Solid game overall😍💕🥰.
