Gotta say, this game feels like a funny twist of the "Papers Please" formula. And it's awesome!
The setting is funny, characters are hilarious, the art is very fitting and I can't wait to have arts for all your "colleagues".
Some stuff I want to point out are that not always potions descriptions are helpful (especially the thief one), some heroes are hard to pinpoint what they are and what they do, and later on, all the green, purple gem colors are rather confusing (but I'm sure you are already planning something).
If you like suggestions, maybe a tool like a magnifing glass (with a nice quest/story to accompany it) to move over the equipment of the heroes and give them a classification would be helpful, especially if you plan to make the multiclass more complex.
Also some coherence of the items' graphic and the shop would be nice, but i perfectly know they are all placeholders.
And (but this only in the faaaar future) add more classes? It would be nice have bards, paladins, clerics...
So far so good though! I can't wait for the next update and what potions you will come out with!!
