Hi, I think this is a great game. I love the energy system, it's one of the few that makes people feel fair whether or not they pay to play, yet makes it worth it for those who want to pay. A few suggestions I have (in order of most to least likely):

1. Currently, a knight needs at least 10 energy to join a party, at which point the party leader can choose to pay elevators for them. I often do this for friends, but friends that do not have 10 energy have to wait a while to charge up first if I do not have any crystal energy to give them. My request is that people with <10 energy can join a party if the party leader agrees to pay for them upon their attempt to join.

2. As much as I love the autogenerated maps by the community effort, I'd like to see more quest and story-oriented things like the three levels related to the Snarbolax. Raiding castles, exploring fields, things like that, where applicable.

3. My final and least likely suggestion is that either the full game be ported to iOS and Android, or perhaps a singleplayer spin-off be made from which achievements in-game can be transferred to the user's main game account. These could be crowns, or maybe just a few promotional items. I wouldn't normally suggest this of a PC title except that this is a java game that can run on OS X, Windows, and Linux, so if the devices have enough power then all it would take is a GUI rewrite and inclusion of the necessary java libraries in the binary.

Keep up the great work on this great game!
