I like the premise a lot, reminds me of Buckshot Roulette! Dealer is creepy and it was fun to optimize a winning strategy. I think the SFX could use work (the evil laugh could use a lil randomizing as it gets repetitive) and it would be cool if there were some more dynamic landing options (like landing on one heals the target but damages the other, or a "jackpot" sort of spin that heals both you and the dealer to full but can only be hit once) but overall a good submission!
