Very awesome! Thank you for taking all the ideas into account - just don't make it neither too cheap nor too easy... I'd have paid 1 Hive for a drone that let's me sleep at night and waters my tree :-D I just need to do it twice to get over the 8h sleep cycle, and then the help kicks in again. After that, I won't buy it for 4 days (4x4=16h) until it starts over. 4 days in which I will keep collecting the rewards. I'd say it would be best to balance the cost and the spending. I can pay 1 Hive for a drone to water, or I can get up at 2am to water myself.

In the end, the game is none-profit. But it will break if there's more outflow than inflow. Even the large drone doesn't cover the outflow. A pine tree is 0.09 Hive/day, which would be 0.27 Hive in 3 days, easily jumping over the sleep period when helped fully. But it only costs 0.24 Hive.

My idea would be to bump the cost to 0.5 Hive for the three waterings, but have a sticker for the tree that you want the watering for, so the helpers can make sure it goes over the sleep threshold. In total, you still come out positive, since you don't need the drone for a while afterwards.

Also, bigger trees need more water and hence more drones. Nobody is there yet, so just saying... ;-) I'd love this little game to prosper in the sense of losing very little, so it can go on.
