What to say... I spent an hour on a single run. I could write a whole story around the last recruit holding the single level 1 turret that was the very first one through the whole 27th round for 20 minutes... only to die tragically at the start of the 28th.
From the 10th round onward, it gets HARD. Enemies spawn out of sight, firing at you immediately, threatening to split your ship in half in a matter of seconds. Shields we're the single thing keeping me alive when i had some.
I feel like knowing what upgrading does for each module would help a lot in developing the ship through the rounds, but as you can tell, i had a blast anyway.
I think I'm gonna go play some more, just to avenge that legendary recruit...
