The story is ok, but a bit too generic in a way. The characters are interesting and I feel like you could have done more with them.
When you choose to use a wrong potion it would be more interesting if the situations would be described and different every time instead of "Regardless of what the potion did". It would also be interesting to see an ending where your wrong choice of potion would make the adventurers get mad at you and quit / get hurt and quit / die. Brutal but a realistic option.
