four things:
1 - i will definitely come back.
2 - if the shop area has npcs make sure the player has time and space to put his weapon away before accidentally stabbing someone.
3 - my problem with the storage was mainly because of two factors: A - there isnt any way to record/search anything about items unless you have them on hand (this could be fixed by adding some kind of encyclopedia which starts blank and fills in as you play). and B - ... i didnt want to throw any of the pets away.
4 - the map generation, while basic, isnt too bad. the two biggest issues with it is that, unlike most games that randomly generate the map, its small, and doesnt change (boss room every x floor, later floors changing theme, etc...). but i suspect that it will change as the development goes.
