That's great you got through it (hopefully not too many deaths?). Thanks for the great feedback, it sounds like you enjoyed it overall. In response to your list:
Damage system: Yes this is mostly from STR and a bit of LUCK. SKILL does have some attack properties when used with other abilities (eg with the Rogue).
Waiting times: I am going to look into this a bit more. I think my keywords are not quite right when looking on stack overflow etc! I would appreciate seeing how you did this in Python.
Unknown: Yes this is a bit of an easter egg/gimmick - I'm glad you found it funny!
Potions: I know what you mean, but sometimes it's more fun to try something out? Similar to how you find properties of ingredients in Morrowind etc. A manual for the game will be coming soon too.
Buy/Sell: Good point, I will update this in future versions.
Mobs: The monsters do scale with the player (apart from bosses), and there are stronger ones in new locations as the game progresses.
Text-wrapping: Good point, I will look at this for future versions.
I'd be keen to discuss further on reddit - I've joined the sub-reddit now! I will make a post introducing the game and then we can chat more.
Thanks again for your detailed and constructive feedback. Your map is great too!
