Opera seems to be working fine for me... Enemy sprites and everything is working alright.
I guess it was fixed? I haven't logged in for the past three days.
Obviously that isn't always the case when you start. But mid and late game, Twin Upgrades just become useless as your insects make a lot more in one second.
1. Get a level 2 tree, one lumberjack, one gatherer, and the home upgrade. Upgrade everything to as high as possible[Including Fishermen] and get the first dragon, then just skip the wave-waiting.
2. DO NOT BUY MORE LUMBERJACKS YET. Why? They'll hinder your gatherers from gathering FISH, we don't want that to happen, and yes, get fishermen now after the first wave, make sure you have at least level 3 environment before doing so, and get 3 gatherers and 3 fishermen asap. And make sure you don't buy the tree upgrades further than 5 yet. The wood hinders your fish-gathering. which is needed at this stage.
Start the game in a way like that and you're probably good to go. Just make sure that you don't buy more lumber-jacks yet, they'll chop down tree's to hinder you from gathering fish. Get more only when you have a high-concentration of fish and all that stuff.
P.S. I know my 'guide' isn't necessarily that 'great' but hey, it works, probably?
