Hey, guys!

We are working hard on improving the game and it's systems and today we've re-made system that allows you to walk the forest through. From now on character will be running by itself and you'll have to be sure that you've gathered resources and killed enemies in time.

besides, we've implemented several fixes:

- Player's animation is improved
- Added sound volume
- Improved tutorial
- Improvide flying enemies
- Improved UI
- Sigils no have prices
- Fixed critical bugs
- Spawns are improved
- misc fixes
