This is definitely the start of something really cool!
Some feedback:
- I'd prefer to have to feed the fire manually. When it automatically takes the wood, it's eating up a building resource that I may have been planning to use for building.
- The sliding movement doesn't really match the character or environment. If you're using physics-based movement (ie. rigidbodies), a character controller might be more in line with what you're looking for.
- A small animation or effect added to the tree/resource node you're hitting would make it easier to tell what the player is hitting.
Good job on this! I can definitely tell you put a lot of effort and passion into this one!
