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.

I love the Building mechanic

The gameplay of assembling parts is very interesting, and this game has unlimited potential!

What a great game you have here dude! I want to see more of this! This is amazing!!!

This is a great concept that deserves some more time put into it for sure! The UI is a bit rough so it was hard to figure out what was happening to start with, but once I got into it it was a lot of fun. I think a clearer indication of how your score is affecting what you can buy, or why certain items are available at different times would be good (I had multiple rounds where I couldn't buy a plain block to put a new gun on)

I hope to see more from this concept in future, great work!

I hate to admit how much I enjoyed this game! amazing work! art, music, gameplay and theme are all wonderful. Well done.
I would hope you continue and expand on this concept. more parts, more direct control on attack waves (I noticed there is a point where the screen is overwhelmed by enemies) This is a game I would buy cheap on steam and sink hours in if it had more fleshed out content. 

Really amazing work!

I like the game
It's quite fun.
The music was a bit repetitive but that's just being nitpicky
What I found annoying was the inability to take a piece off if I misplaced it. Or if I build something I don't like after trying it.
It would be way nicer if you could also take items off and put them again. I think at least after losing a round there should be a chance to revert the last set of changes 

I would have also enjoyed having more space to put weapons as the spawn for blocks feels quite scarce. And the difficulty curve ramps up quite a bit, if you build your rocket vertically you lose quite fast.

I also think more snappy control would have felt nicer as I often felt like I couldn't control the rocket.

All in all, I did play quite often and got on top of the leaderboard (for now at least). It's a fun game. Good job!

Really interesting game. I couldn't figure out how to attach the guns, but I'm going to come back and try to.
