Awesome entry! I spent quite some time fiddling around and had good fun! Some things I noticed:

• Would have liked a keybind for Target/Clear all
• More interaction while playing, maybe more movement abilities, currently I simply circle the enemy ships, I didn't feel like I could do much in terms of evading incoming shots.
• You can never have enough different block types :D
• Not sure about the Tactical pause. Certainly depends on your vision, without that the game would be a lot more action focused. Then again, one can simply choose to not use it.
• Show the health of modules which are not at 100% without hovering over them. (Maybe only while paused?)
• At some point the move controls got very unresponsive and I wasn't able to steer/accelerate properly anymore. Pretty sure it was because of my ships size, some kind of engine power to size ratio in the UI might have helped.
• I found the "static" layer of stars that follow your ships every movement kind disorienting. The ones behind, which create the parallax effect were great though.

I could actually see me play a few rounds of this here and there outside of the jam, good job! :)

Well this was definitely a unique one amongst the jam games, and really sucked me in to play a lot of it.  Though it definitely got monotonous after a little bit since I ended up with a behemoth of a ship with just endless turrets and everything.  I do think it wasn't supposed be actually usable though since the turning and straight directional movement stopped working, but diagonals still did (good ol' annoying diagonals).

A few points though to be more specific:

• The base systems are great so much variety, you can make enemy ships with it obviously, and change up the players ship to fight in different ways.  Focus on front defense and speed or all round defense etc..
• A big problem for me though was the monotony of it, since you run out of new blocks relatively fast.  Not to mention there's really not too much interaction with the game directly since you're just moving and targeting stuff.  Or just tanking sometimes.  So more blocks types (obviously) would probably be a welcome change (but it's a jam game sooo) 1 or so per level probably.
• Another thing is the fact that there's not really any landmarks besides the main portal.  They would definitely help spice up the gameplay, maybe some asteroids, or an enemy base or two?  Planets maybe but then I feel like they'd need a bit more variation, whereas asteroids are simpler.
• I feel like it's the same point but enemy variety was also a bit lacking, obviously a jam game but I figured I should mention it, though they did seem like they tried to have some interesting setups so maybe that's more down to the incredibly broken ship I put together.  

Alright well, now that I've nitpicked.  This game is coool!  There's some awesome ideas and some awesome execution, just with some variety missing in my opinion.  I'll definitely be coming back for any sort of post patch tho.

Great game!

Attaching more modules and growing my ship was super satisfying. I got a little carried away, and ended up with a turret behemoth w/o engine modules, haha

I bet writing code to manage all the modules was tricky, very impressive for a game jam

My most favourite game from the jam! Just well done. Like everything, from graphics to gameplay and fits the theme perfectly! really crazy to think this was done by 1 person? Wow just wow..

Great game! it is definitely challenging. I like how you can strategically rotation yourself to provide protection for your ship, super cool mechanic!

I think it's the most fun space combat game I've seen on this jam ! I have seen a lot of similar concepts, but I think this one works particularly well, with the active pause system and the ability to rebuild your ship as you want. I think it would need enemies a bit bigger, to force the player to focus weak points instead of just spamming the core, and make full use of the cool mechanics. 

Graphics are pretty functionnal, Maybe the ship base could stand out a bit more, to show better where to shoot, for many enemies I destroyed what I thought was the core, only to discover that the core was actually right next to it. But that's a really minor complaint.

Very cool idea and excellent execution! The one thing I'd love to see more is to have a bit more hotkeys for things, instead of having to use Q/E to rotate, maybe rotate by have the ship looking at the mouse. Or have middle mouse button act as a "Target all" hotkey or such. That way I wouldn't have to give up full control of my ship with WASD to rotate or have to finnick with my mouse to get my turrets to target an enemy.

Those are just minor gripes though, your core is really well done! Are you planning to develop it further? I can imagine this kind of game on Steam with some more content and features. The base is very solid! Excellent job!

Cool concept that was really well presented :)

It was easy to grasp and fun to play :)

This game was so fun to play that i think i played it for like 30 minutes. Really nice take on theme.
One problem i faced was that rotation on some point became so slow that my ship did not even move. I'm unsure if this is a bug or intended like this. Anyway a rotational engine module would be nice.
Another thing that would be amazing is binding attack command to a button on keyboard (Like in Starcraft 'A' to attack)

So satisfying to make your ship larger and larger! Had a lot of fun playing it

This game is quite underrated. It's a lot of fun to play. 

Though I think I noticed a small bug. When I'm really big, pressing only one movement button is really slow, but pressing two (for moving diagonally for example) I move like 5 times as fast.

This might be my favourite game of the jam. I love how you can build an absolute monster of a spaceship. 15/15!
