The Dink Network

I encountered something that could be considered as a bug, it is a solid problem with the screen borders. When I go into the sea from the main island, go down at the same screen and then try to go left there is a big problem with that, because the screen mostly won't let me go there. I could do it only once and on another screen down I found one of the poops and a defence potion which I couldn't pick because I couldn't reach it. Besides, this screen is very badly designed, there are a lot of "invisible obstacles" and when I wanted to go back the same way I couldn't because the screen won't let me out, so I had to load the game.
