Seems to work pretty good so far mate
I couldn't really find any bugs or anything, so that's good... and I like how the player has that shoulder sway thing when you walk around. As far as being able to only pick up one item at a time... I have no idea I can usually at least suggest some pseudo code, but I got nothin'.
Sorry man, my brain isn't working right today.
Keep up the good job so far though, this game should be a lot of fun to play.
