Thanks, Danny! The more games I make, the more I realise that a big advantage you get with a longer development time is the opportunity to rebalance things. If we weren't in such a hurry, I'd definitely have tweaked things so that the Cloudwarden and the Fuzzballs aren't as murderous as they are. :D
A full version could be interesting. Would it be one piece of folklore built over the course of multiple levels, or a new bit of folklore for each level, with the outcome of one level subtly influencing the next? Another potential project for the pile!
