New stuff:
1. Improved: I reworked the fog transition to make it look better.
2. New: visual feedback for when the terrain damages the explorer.
3. New: added a smaller health bar next to the explorer so that you don't have to look away from the action to see how much health you have left.
4. New: added a death animation to the explorer so its more clear when he dies.
5. Improved: travel speed scaling was reworked, now the explorer should not move too fast or too slow, even when upgrading travel speed.
6. Improved: changed the creature attack sprite.
7. Improved: changed the explorer sprite so that it has more personality.
8. Fixed: enemy wave creation and delay was not showing correctly in the UI bar at the top of the screen.
9. Fixed: visual depth of the explorer was broken. Now, objects that are further away from the explorer will appear behind him. Objects that are closer to the camera will appear on top of him.
10. Fixed: sometimes when you clicked where to move the explorer, he glitched near the desired stop target.
