New levels and UI improvements!

Thanks to everyone who has played the game so far. I've been working on setting up level progression and I'm absolutely stoked to say that it's done and it works a treat! I've added 4 new levels to the game but over the coming days/weeks I'll add more with different themes/new assets.

Additionally I've improved some of the UI and attack feedback, especially regarding special moves. 

If you've tried the game before I hope you enjoy the updates and thank you to anyone trying for the first time :)
