I'm finding this game difficult

[rpeg]

In regards to the units, is there no way to purchase units and keep them at a location where you can use them later? or do you only have access to the units in your team, after you've purchased them? The reason I ask is because it seems tedious to me having to travel to certain far locations just to buy a unit.

Also, I think the zoom out option is pretty limited. I wish you could zoom out more. Are there any hacks for this? Thanks for your help.
