Small Update

Patch Notes:

• added music to the game
• updated the portal to the next level to a hole in the ground (still a placeholder though)
• updated the shockwave visual
• made the font in the upgrade menu bigger
• fixed the bug, where combos wouldn't be turned into gems, thus not ending the turn (hopefully. the button is still there in case it still happens)
• fixed a bug after hiding Gem HP, then loading the next level and showing it again
