Really good idea - when the Jam started my first thought was also to implement seven playable characters in some way. Seems like a nice puzzle platformer in that respect - only wish it would start off a little easier, but it's fun!
The difficulty is not a problem, but a little tutorial in the beginning on how to play would be great, just so that one can get used to the mechanics and logic before failing very often in the beginning. Just as a suggestion, but I like difficult and I liked it
