im having some issues with the game. i downloaded the current version found here, however on the main menu it tells me the game is out of date. next. i cannot pick up the green lube bottles at the merchant's counter nor can i cycle anything i was "given" in my inventory using the mouse buttons, the scroll wheel, or the 1, 2, 3, 4 keys. lastly. in the first level, i cannot seem to get the ladder to spawn in order to finish the first level
