Nice work!
The AI was quite good and it was bothering me (in a good way!) when taking back my stuff EVERY - SINGLE - TIME but I won! ^^ (What an earape though when a character dies! xD )
It's funny you can let the AI fight so you can also play a gamble game. .. HAHA you didn't know you created another genre did you?!
Very simple controls, easy to pick up, simple graphics, everything is in simplicity for the gameplay. Good job for a one man dev in one week.
