Heartbeat Update

Reworked Lives !
Now you have 3 lives when you start a level and the Kyvedy Flame restores one heart each time you use it! The new mechanic is quite fun as you can use the Flame to both kill monsters and restore your life.
A proper Tutorial !
Instead of having the basics explained in the first floor of Guardiah, now each time you start a new adventure you will enter the Tutorial Map for a quick tour of the game dynamics. There you will find NPCs giving you tips and once done you can access Riverguard from the World map any time you want.
[h2]A lot of quality of life improvements[/h2]
In this update I made a lot of improvements to the gameplay and went through any level to fine tune it and make it work with the new mechanics. The result is a game experience less "rogue-like" and more enjoyable as a journey in a fantasy world.

Aaand that's all for this update !
