I just released a patch to fix some of the issues noted as well as added a mechanic update.
1). Build size has now been reduced from 700 Mb to just 40 Mb. There was a pesky little file in the project folder I decided not to use that was large but was still being included with the game build. Oopsie. :)
2). I have added Left Mouse Click as an option to interact. Thanks for the suggestion "Odin's Wholf".
Hope everyone is enjoying The Most Boring Game Ever! Cheers! :D
