Well...
It's a pretty difficult game, not gonna lie. The curve is steep and maybe I'm just tired and not reading, but it didn't seem like upgrading my units did anything, they still did horribly against the later enemies. Still, I'm not going to give you a low score for a job well done.
Gets really difficult after a while, but the idea is superb.
The orbital lances usually work to my favor, even if I have less health, so I usually try to stick it out until then.
Unreasonable difficulty
It started out fun, but the difficulty curve is just insane. It went from reasonable
with the first two bosses to insane with the next. Snipers do too much damage for their range, units move too slowly, overall it just seems unpolished.
