Wow, I was surprised by how complex this game is and polished. It seemed impossible that you made this in 4 days and half, then I saw that this is very similar to your Steam game and most likely you started out from that, or how did you pull it off?
Had fun playing, the feedback I can give would be that wood seemed like the most limiting resource, which is understandable, but a better production option would be great, also the storm seems rather harsh, should it really destroy all buildings in it's way (I know you can block a few being destroyed)?
Great stuff as always, congrats!
