This is essentially the same as the Android/iOS version, but you'd be forgiven for thinking that this version is level-based, because it makes you play through levels to reach a target score for quite a long time before it lets you play the game on "endless" mode, which is probably all you wanted to begin with. This version also makes you build some kind of "permanent" capital city on a different island. I'm not sure why anyone would want to do that, but it's there and it's not too distracting. The capital city is also your hub for sailing to other islands, each of which is one of the modes from the mobile version. Overall it's nicely put together, and it would be hard to criticize if you hadn't played another version. You can still close it and resume your game later. I think that using the Item Store is cheating, and that feature is prominent in this version. Each mode should be available without this "pay to win" feature, even if it's not real money. Thankfully the GOG version does away with micro-transactions, making it a "proper" game.
