it was fun, i admit, but there have been several annoying things, like the frontiers of trees or lakes, i often walked into them - thinking i still had space left. i also think the pets should be stronger. currently they are no big help ^^
imho, if the importance of pets, pet attacks and enemys ranged attacks would be a bigger aspect, i also would increase armor value.
(maybe add why somebody should buy a better weapon or armor - write down what makes it better - higher DPS, higher ranged defense or whatsoever. it will be awesome!)
after all, its a lovely idea, and i enjoyed it - its kinda addictive, hehe :)
i hope you keep up your nice work - and make it into something really awesome. theres alot of potential!
