Thanks for the quick response! The new build is still a little slow regardless of resolution but runs much better! (I can play it now. :-) )I see it's also always windowed instead of full screen, too.
Awesome! Glad it's playable now. I made a few changes which aren't present in the Steam build. I updated the NW.JS files as well as a few other small things. Steam Achievements are operating through an older version of NW.JS so I'm suspecting that it was causing some conflicts when the game is running stand-alone on itch. I will try and fix up the Full-Screen difference between the two versions soon. I just wanted to see if I was on the right track in diagnosing/fixing the issue. Any other issues please let me know!
