This was an incredibly good concept! Though I almost gave up on it instantly since I was trying to drag a gun onto the ship without adding a block for it first, and thought the game wasn't working, I'd love to see just a simple breakdown of "place down a block for a weapon, place weapon in block, launch, kill things, repeat" either in game or at least in description.
- Unlocking new upgrades as you go, and building up your ship was incredibly satisfying.
- Effects and sounds were all on point, only thing missing was screen shake
- I think it was a bit too hard, most waves I spent half of the wave just dodging things since I barely had time to shoot. Would love to see enemy speeds slowed down 30-50%
Overall great gameplay experience, exceptional idea, and fantastic aesthetics / audio. Would recommend.
