I love this game, I can hardly wait to see more. There are some things I'd like to see in the future, like an armor tab, more plot to tell us why we're wandering about befriending creatures. Also, I'd love to see us being able TO befriend ALL creatures. Like, instead of being able to befriend some but not all. I get some of the creatures may be very powerful, but at least put in a food that's rare to make it a rare catch. More towns would be nice, and maybe some signs to explain new aspects like "You can climb up ledges this way". The Cactis also upset me, like it wouldn't let me by at points. I had to repeatedly try different angles to get around them. Give us a way to damage the cactis like we can damage rocks. Let it drop "Spines" or something that can be used for crafting. The bigger the Cactis, the more reward for destroying it.
Another thing I noticed, was that the creatures you've ALREADY tamed will sometimes stray off or halt in their movement and won't follow you. I tried feeding them at times like these, but they still acted out. If you want to keep it where we keep having to remind the tame creatures why they're tamed, perhaps give a punishment and Reward system to help let us TRAIN the creatures so they stick close by no matter what.
