Hi I'm sorry about this but there is no real way around this as the issue is quite tricky. Less memory cannot be allocated as the game might run out of memory halfway. WebGL have some serious memory constraints around so we are working on optimising as much as possible (but this is non-trivial work and is really just problematic) and so this will take some time. Alternatively, you can try playing on Web Player or refer to this for more info: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.reddit.com%2Fr%2Fincremental_games%2Fcomments%2F4m7vav%2Fenchanted_heroes%2Fd3wnxu6
