This is an amazing concept, and it was executed brilliantly, too ^_^ I like how your actual HP is your currency to upgrade yourself, but you can't just blindly waste it since this game is centered around gambling, casinos etc. so you also have a high chance to win nothing :^ That's clever.

I also liked the gameplay. Despite you just fighting some brainless, big guys and some angry grandmas, it's still pretty epic and fun! :D

You did a good job at this game, it stays true to its theme and is just overall really fun ;^)
