Heyho, whiteRocket!
I think it should do the ip/cookie thing internally (so you can play only once), but you're right that we should've communicated it better ingame 👍
And yeah, the base gameplay is the same - we've released our final PinkOball Tentacle Tower version just before the jam and all we could think of were balls :D But most gameplay elements (bumpers, dialogue etc.) were new.
Stay funky,
Dez
