It's an alright idle game, but it has a major problem: Stats only show up in the info box, and we have to mouse over the unit to see the necessary stats.. It would be nice and extremely helpful to see how much cash, number of units and their respective cost from the get go. Depending on the size of the font, there should be room in the boxes to display the quantity and cost (or unit availability).
Some improvements would be tightening up the interface, maybe add in a reset system of sorts, and a back button for if we decide not to invade the next location due to something like the lack of units.
Other than that, it's a decent game that just needs a lot of work done.
