I really don't like this error system in this kind of game. I like to fill it and if it not fits correct it myself and not getting said "this tile is wrong".. 3/5
The game could benefit from technology to combine transport of multiply types of resources (like pipelines or with energy cables), and a system to build on water like artificial islands
The -25g at drinking seems to be a second potion.. so he drinks one of the shop and one of the inventory .. (for 100hp). I like that change it makes him strong enough to survive without buying anything. 4/5
the later levels let you fill out the level without feedback on mistakes, thanks for trying it though
