built a "real" level. Still very repetitive for now, easy to get lost (no more door, they'll be back)

changed movements square size from 1 meter by 1 meter to 1.5 meter by 1.5 meter

added an objective to win: find the treasure chest

added possibility to get hurt and lose. Walk on two traps and you're dead, the game restarts automatically.

added UI to show life, total collected coins, total coins in level, objective, and keys

optimized textures quality, and size in the world

reduced download build size
