1. The movement feels pretty good. I don't think you need to increase the speed, but I would like a jogging mechanic.
2. I think the bears are a bit too small for the humans, and the area that I was able to explore was fairy populated.
3. I could not figure out the throw mechanic, since there were no instructions or opening scene. I was only able to figure it out through trial and error. the aim feels a bit clunky and I could benefit from a reticle to aim.
4. I think what you have in the question is what's needed for the game.
5. Honestly, I think the bears are a bit too small, and I feel that some textures for the play area can improve the game overall.
