A very surprising and great game. Loved the ship building, even though it took me a bit of time to understand how it works. Starting money seems a bit lackluster, but at least you have a very cheap and OP Wiper weapon and a free lazer weapon - so that's cool.
The thrusters need some sort of visual indicator for "where it's thrusting". I did figure out that "fire comes from the black notch", but it was a bit of an trial and error process.
Took me WAY too long to realize I need to go "under the blanket" for the level to start - because at first I was trying to fight the blue pillars, especially since they have damage indicators.
Ship may start thrashing around the builder screen if you weld diagonally placed elements to each other, so that may be a bug.
Definitely needs some balance, cuz I don't think you can get too far with the starting money and without the "cheat" weapons.
Other than that - a really, really cool idea and a great execution. Loved it, and looking forward to the next demo!
