First of all, I like this slow idea very much!
I have one game which is double-slow. The game is about frogs and they are not very hurry. Playing with them you should be patient and precise rather than fast. The second slow is because I started this work a year ago. Having my family, job, friends, etc. there is still few things to introduce. So I am afraid the game is not valid for this jam (work started a year ago) even if it fits the slow idea :(
But I wish you all the slowest!DRM
