ok i've played it again now that i know how to beat the spin the bottle minigame, floor 5 is awesome, it was a really good break from all the minigames and i felt like all the bonking against obstacles had prepared me for the fight, the mechanics weren't that clear but it was really fun! the massive lag spike that happens also happened to us btw! if the star particles are GPUParticles2D webGL messes up preloading them so you have to spawn them with a transparent modulate once while the game is loading to make them preload.
Definetly added to my enjoyment!
