Thanks for playing my game!
Sorry for it being sooo confusing tho :/
-Yes it's meant to be SSHOP ( Station Shop but it kind of doesn't sound futuristic enough )
-You can exit the shop with X or ESC but forgot to add it in the instructions on the game page
-The little yellow square is a bug, you can select on your hotbar with 1,2,3,4... but for some reason it gets moved sometimes (dont know why)
-To plant you need to have selected a seed that you buy from the shop and then press E on the empty farm land
Will maybe fix the game and add some things later, if so please try it again!
