1. I created two games. When I half way my game want to go back to the main menu and then load the other game or the same game for that matter, then the game hangs and I can only kill the program.

2. One time after killing the baddies around a "shop boat house", I didn't manage the kill the guy that sits at the rudder and he got stuck in my home made boat and kept pushing it out of sight. Isn't it possible that it finds another way around objects. Fish do the same.

3. Once a whale flipped my main boat, but the only way to flip it back is to activate the crane which was naturally also underwater. When trying to get the menu on the crane, I kept being pushed to the surface of the water. When holding down the control key, I simply sink too fast.The only way to stay static in the water is repeatedly hitting the Ctrl key, but as soon as I open the menu of the crane and move my mouse to the Flip Boat button, I can't click Ctrl in the mean time as it closes the menu. Hence it is undoable to flip the boat when it is upside-down.
What was your reason for letting the player be lighter than an actual human and float up to the surface? Is something wrong with using say the Space bar to swim up and otherwise stay at the level you're at. Also when hitting sea weed, this is extremely annoying.

4. Not sure if this is intentional, but when harpooning a whale it manages to get loose after wiggling and I don't think harpooning in itself will take away its health x%.

5. A more serious problem. I had created a very big pontoon, which I had parked at the -900, -900 Carnivorous Island, then when I after a few a few saves returned, it was gone. I spent a very long time building it. Since I can't catch whales with its crane, I might as well create a floating panel which I drag along with me all the time. Now I have lost 2 hours of saves.

6. Another problem when I returned to the island was that it said I could only have one satellite dish, even though I never built 2 and just planted it at the island.
