Cute. That’s the only plus.
An idle game is really only measurable in the feeling of progress, and this game can’t manage that at all. You can improve your crew, add speed, number of units, but the choke point is the resources. You’re stuck with 3 resource points, meaning getting more than 3 units is completely pointless, and there was no way I could find to increase the number of resource points with the only visible UI being the Upgrade menu, which has the aforementioned upgrades. To make it even worse, it makes no progress when the app is closed, so the only way to progress is sit there with the app open, watching the units stand around until the resources decide to refill, see the three of them walk over, take the resource, and walk back. It might make a decent screensaver, if only the resources didn’t refill so slow. Beavers are cute though.
