Did a quick test of letting the game run and playing it for a bunch of days and I got up to a maximum memory usage of 110mb, which always dropped back down to 64mb when the garbage collection kicks in.I know there are leaks, but in my experience you have to play for a long time to get it to crash.Is your browser/flash player up to date? Someone also reported crazy memory usage in chrome...
When looking at the game from a technical/theoretical point of view, all games will have some sort of memory leak, this one seems to be caused by the time it is open, what kind of operating system you are running off of, what computer type, what browser, that kind of thing. So.. Just make sure everything is up to date, and you should be fine. Also, try to make sure to close it when not in use.
I Am current running chrome, but i dont know if it will leak for me, because i have a good computer and windows 10, anyway, SO happy you got this made, and it was worth the wait in all ways, shapes, and forms.(?) friends will be pumped.
