Strange behavior in the Alpha version of the game. I tried putting old entities into GameguruMax. There is what worked, there is what did not. But walking in the water is cumbersome, the projectile projectile sleeves bouncing on top of the water. On the other hand, the bird flies nicely and the shark also bites. Although I climbed inside. I also attach a short video.
