0.2.0 new builds, water interaction and new hammer tweaks

new builds, a plataform

and a ramp

free move now-w- way free control of the building

a menu:)

some tohers tweaks like

1-you can kind of swim now ,_,

2-hammer animation, is awful but i'll try to fix it

3-plants some times give  2 fibers instead of 1

and i think thats it, probably the next update will take way longer...  time for world creation and save (i'll make the terrain have different forms way later)
