The ARROW Keys will be to move (When I implement the actual game part). X to interact, and Z to move the dialogue forward.
This is my first "watch me make it" project EVER, which means that I'll be adding onto it while it's public. If anything doesn't seem to be working correctly, just try hitting the green flag again. If that doesn't work, please let me know. Also note that as of writing this, it is in version Alpha 0.5, which means that it is in a VERY early stage. Thanks to @pococikapusta for the text engine that was already there. This is also my... third project that I've made public. It's sort of weird, because I make a lot of stuff, but I don't make it public.
