New improvements (Post-Jam update 1)

This update brings lots of improvements that time did not allow to be put into the initial jam version, among which:

• The character now loses life in a more smooth manner with a gradient, thanks to an improvement in its shader
• Improved balancing overall (monster spawn, item drop rates)
• A campfire now needs only 4 wood pieces to be built and its cost is shown in the keybinds overlay on the right side of the screen
• Improved transition from main-menu to game
• Arrows don't stick to dying enemies anymore

Things left to fix:

• Bug that sometimes occurs between the player or snowmen and snowpiles
• Replay button!!!

Thanks for reading! Thanks for playing!
