I've been playing online a bit, and some of these games can easily go 14 rounds - which would be two weeks. Is there any limit on how long a game lasts?
There's no exact limit yet, i only wrote in the Q&A that if a game goes on for a recognizably long time, then i will intervene in a way that will make it shorter. However, i think that not all rounds will last 24 hours, because if 2 players who face each other and I are online at the same time, i'll advance faster with them. Also i will update the battlefield as soon as i can, so if both players send their combos in early, their round will be shorter.
Furthermore, i did plan on making the deadline for sending in each combo to be 16 hours long, but the people in chat rejected it.
