Demo Update 1.3

Hey all. I've made some changes to the demo, specifically regarding the difficulty and level design. 

• I've cleaned up the tutorial level so it's more accessible
• Introduced three extra levels to the demo
• Some other minor bug fixes
• Extended sinhala localization to the other levels

I also hope to put it out on Steam soon. There might still be bugs and minor issues with levels and localization. These will be fixed soon.

Thank you.
