Thank you! :D Maybe we’ll fix the difficulty in the next update.
The difficulty isn't a bad thing, i kinda like the challenge and it's not too bad once you get to it. But for more casual players might be a good idea to lengthen the expire time on items. Over all it doesn't detract from it at all, which is pretty dang amazing and hard to do!
Anywho can't wait to try an update if you are planning on updating and adding onto this project, :D
