hi, thanks for the feedback,
about map size, I think you'll like the next map I'm working on, it won't have borders, infinite size xD
about improving the appearance of the maps, yes, it is in my todolist to add elements, to improve the atmosphere as you commented
about losing items, it's something intentional to encourage their use and also increase the difficulty, but you're right, this behavior is obscure, I'll put a message as you suggested
again, thanks a lot for the feedback ;)
