Getting enough money from gambling to buy things in the gift shop requires holding down Enter on a slot machine for an extended period of time. This is boring, and it leads to you missing corruption prompts (view corruptions is a y/N prompt). It would be better if you were prompted for how many games you want to play (or how much gold you want to win), and then have all of the gambling happen immediately. If the PC gains a corruption midway, stop the gambling there.
