Just uploaded the new build. Please download the file that says: Mutiny Island 1.4.3 (LAG FIX BUILD).zip
Run Game.exe instead of NW.
Please let me know how you all go.
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!
Definitely on the right track! Improvements for sure, the FPS is still choppy when outdoors (seems to be fine when going into the rum hut in the starter area) but a lot more playable now, doesnt outright affect gameplay but i thought it was worth mentioning, there's still a big fps drop at the start when you're getting hints.
