for those seeing "memory leaks" double check your adblocker make sure you allow the kong game server but not the ad server. kong has cryptomining scripts being served in the ads which is causing the massive memory loads you are seeing. (first noticed this on Squid Ink and worked with the dev to try to isolate and the memory issue was all in the ads kong is serving..)
The Offline Continuation is hugely Exploitable. It tracks on Local time not against a server. which in turn makes it modifiable, and exploity, on slower machines at the higher ends of the game even having the window closed for a few hours on restart the offline calculation will crash unity.
great game the super spawn catch up wouldnt be that big a deal of you could set units to hold position like a defensive would also add the strategy do you amass troops and wait or just go all out
