UnitSimulator

This game is by no means where I want it to be, but it might be something you could vibe with in the background for a few minutes.

The basic controls are:

LMB (Select Units) w/ Shift Modifier to add to currently selected

RMB (Task Selected Units) you can send units to gather from Trees/Rocks or to load resources from the Stockpile to the ship

MMB (Buy units) you get more currency when the ship takes of and comes back with resources

Q/E - fly down / up
