I don't know if you saw but this is one of the older versions of this game. The game is up to 0.0.7.1 now. Though if you're still looking strictly for a duel simulator even 0.0.4.0 fixes a lot of the bugs from this version while also looking way better. This version was about a year and a half ago so I don't remember specifics bugs fixed but I did say at the time of 0.0.4.0, "I can't believe I thought milestone 3 could even be considered stable." I keep these up for posterity, but I don't have much plans to bug fix each version.
