could you add an option to sell unwanted items because i had 4 steel swords and 4 steel plate armour and then i built 4 of each for the mythril class but all i could do was discard it, im not saying make them upwards of 100 gold each but maybe 50 or so, so it doesn't just feel like a waste. other than that great game
Unfortunately, a lot of games will do that as they store the game save in one (or more) places -- LocalStorage, IndexedDB, or cookies (that's basically the 3 options you have for WebGL/HTML5 games). The saves for this game are too large for cookies, and it actually saves it in both LocalStorage and IndexedDB. If you're going to clear your history, you'll want to get an export code before clearing your history.
There will be new gear eventually. I don't have plans for new school buildings yet but it is always a possibility.
