Update v0.4.0.0(v0.4.0.1 small correction)

Update v0.4.0.1

This update adds one last game mode, the game contains 3 modes (idle, survivor, and boss battle). The base of the game has been created, now it's just a matter of refining what you already have. Deciding to mix 3 modes in the same game to create a different one, and each mode depends on the other for progression. From here I will improve the bosses, enemies, scripts to improve the game.

I would be grateful for any feedback.

Small Correction:Boss number 1 was not showing up
