No one was on the server when I tried it but it seems like a fun idea. It might be interesting to add some acceleration to the character movement to make it feel like they are on ice (even though they are on a snow field).

Hi, thank you for the feedback! Actually adding ice field (with acceleration) was in our TODO list on the top before submission. Unfortunately we weren't able to add it in time :(
Regarding empty server - it is a problem, there is no fun in this game if noone is connected. Probably you could arrange some game sessions with your friends :)
