Stellar game, as TotalBiscuit might say. The only thing that kind of bugs me is that you should be able to try out all the ships in Solo Practice. Other than that, everything is just right. The support ship's heal is a bit high for that cooldown, but that is overlookable and probably wrongly handled by me..
There is a bug though. You can click on a shape to grab it then hold with the mouse on another shape and release the structure and it will stand in the air. Impressive for a Ludum Dare game though!
I swear to God, the Bottomless Pit sign is the most clever trap in-game. I bet more people jumped to see if it is really bottomless than were killed by those wimp gatlings...
This was starting to feel a lot like Captain Claw, until I started shooting revolvers and TNT at them, hurled powder kegs at crossbow-toting bandits and noticed that your fists are the most deadly weapon in the game.
