So many valuable suggestions! Thanks for your feedbacks.
1 & 2. New gameplays about store your item is under development, which will differ much from current one. And hopefully, it could make things better.
3 & 4. In delveloping version, ladder and pillar hold 9 rafts already. And while we play and test, it is more reasonable for a pillar to make the raft below hold no other things.
5. Weapons and clothes disappear after a while because of their durability, which is a temporary design, also under redesigned.
