Hey what browser are you running it on? Perhaps I can do some last minute optimizations? And where do you notice the lag is a specific phase in the game or just always?
Alright I uploaded a more optimized build and tested it on safari. Safari still has some visual issues and its not as smooth as firefox/chrome, but hope its more playable for you! Perhaps Post-Jam I will work on some more optimizations but with 20 minutes left I dont think there is much more I can do haha
