I played it again and now am busting rocks with my upgrades and this game is just too good! Love the mechanics, the art and the general feel! The only complain I would have, and it isn't one really, is that I feel like I would like being able to pull more on the rope to go down a bit faster at times, could be a consumable item but I think it would add a little more interaction with inputs and would allow some creative visual feedback on the game. But do not get me wrong, I am deeply impressed by your game...what am I saying... DEEPLY HOOKED! Also you get my vote for making such good art with paint.net.
