Ah, I think I get what you mean. The islands themselves don’t take any damage—which, now that you mention it, could’ve been an interesting idea. Right now, the system works so that you lose when you run out of Snorbles. The islands don’t affect your lives directly.
The current setup kind of encourages focusing on a single island, which in hindsight wasn’t the best mechanic. It would’ve been better if the Snorbles spawned randomly, so that strategy wouldn’t work as easily.
We actually had a third character planned, meant to support the other two—that would’ve made the island system more meaningful. Thanks a lot for your feedback!
