Hello, thanks for playing!
I will take note of those issues, thank you for pointing them out.
In terms of crafting, originally I wanted you to be craft and change equipment for monsters as well, but time constraints cut out that plan. So there should be plenty of room for more items to craft in a later version!
I agree, your party can get very powerful when facing enemies, as those enemies would have the monster base stats. I had hoped to allow for battles with multiple enemies to counteract this, however again I ran out of time and didn't have the time to implement it. (I had to make sure the interest system would work with multiple enemies)
The boss was a big struggle during development, with every playthrough it's difficulty would change drastically based on your party and the boss's RNG. It will be something I will work on improving a lot in the future and hopefully be more interesting to fight.
I'm happy you enjoyed it despite it's flaws, thank you a bunch for the feedback! :D
