This is the last planned demo update, from now on all updates will just be done in the hidden development branch. (Which is sort of like a closed beta). If you would want to help out to try it please get in contact with me on the discord server (link is in a sticky discussion of the game).
This update contains:
The fisherman quest rewards are finally working. As you can see in the Collectibles tab your fish will be stored there when you catch them (after you've found the fishing rod, obviously). And you can hand them in to the fisherman when they have a silver star next to them as well as a gold star. For each fish there are two rewards.
The interface has been changed a bit with clearer colors on the gold/bombs/arrows in the top right because it was really difficult to make out what they were when the background was black before.
All the colors of the water has been changed into a darker shade of blue instead of the old baby blue. There will be graphic updates in the future (but not to the demo) to make the waters a bit animated like the ocean.
