Hi guys, I saw this game on youtube and it looked interesting enough, so I bought it. Its obviously in a rather early stage, but it has a lot of promise I think. There is a lot of things that can be added and I am sure will be if you three don't loose interest (and I hope not), but there is one thing in particular that is bothering me.
When you build a planter it automatically comes with soil. I would think soil would be one of the most difficult resources to obtain in the middle of the ocean. Obviously, even if you can get to the bottom the salt levels would be way to high for anything to grow in the soil from there. You could do something with purifying maybe, not sure how that would work. But you must be relatively near to land considering all the resources that just float by, so I can imagine every now and then you might see an entire tree, including stump with soil (even if I feel this should be a rare or even very rare occurrence). There will be some salt pollution, you could toy with that by making plants grow at a reduced rate or not being entirely healthy. Either some of the time (matter of luck, or in a later state due to available equipment maybe) or all of the time.
You could do more with this as well. For example, animals have been known to move between islands by hitchhiking with trees. Maybe if you are very lucky you also get an animal. At mid to late game, poisonous spiders or snakes can be milked for poison to lace weapons with maybe. A monkey can maybe be kept for fertilizer. I am not sure what other species have been known to travel this way, but it might be something to toy with (obviously much, much later).
