Very cool prototype. After getting used to it, steering the boat while walking around is really cool. Of course this screams to steal ideas from Sea of Thieves and to make the boat react to the waves for that seafaring feeling.
The first "level" already feels a bit hard i'd say, since those headless chicken creatures soaked up my ammo and there was way too many dudes with shields. I barely had any ammo and health left when i left the area. Before leaving i died multiple times, which always made me respawn at the camps gate where those baddies ganged me up again. I think i died 5 times until i decided to run away.
After that mission the menu said i had 4 mutagen (i think), so i consumed, had 1 left and 1 point for muations. Maybe a bug? Because consuming the last mutagen gave me a point too. So either the initial 4 were a display bug or something else is off.
