oh wow thanks for the feedback!! the point about the all or nothing style is really good to know, that's something i hadn't even considered - i tried to stress that not succeeding was okay, and i think that probably made it easier for me to miss some polish that would make the challenge more engaging. i would love to evolve the gameplay in some way as the game goes on (i had an early thought about unlocking different floors with new mechanics but didn't have time to put all that in!) and if i continue with this game i'll definitely keep that in mind!
