Ah I see! In the first option, the storm will need to circle back to the beginning. Currently the storm doesn't do that and only advances, it cannot go back to chase after the buildings that survived, but I wonder if it should. I think only then will the first option be viable.
As for the second option, I think taking more time to destroy the turret just means the storm is stuck there longer as it's like giving it more HP right? It just slightly reduces the reliance on a shield, but it won't be able to shoot behind as it will always get destroyed.
And yep! Tomorrow I will be uploading v0.6, a new version of the game containing Storm HP, new defense buildings, a dash ability (via research), some new research related to the storm, the first island scenario, as well as a lot of rebalancing by making the storm come earlier, and arrive faster each time! I look forward to finally be able to update it! In fact, I'm already working on v0.7 which will release storages :)
