Sadly I struggled very much with understanding and playing the game. It seemed like the game ran a bit poorly in firefox, edge worked a bit better, but I also struggled on there. The controls didnt give much feedback, so I couldnt tell if I was doing thing right. It also seemed like sometimes I could place, and sometimes I could not and I had no idea why. Once on edge I ended up building too many thruster, and as such didnt get any resources any more.
As you might imagine after about 5-10 minutes of struggling, switching browser, mashing buttons until thing worked, I was not inclined to play for very long once I figured it out.
Please don't take this too negatively, I know full well how hard it can be to iron out kinks like these. Objectively looking at it, you actually made a really nice game. Its just ashame it had such a high barrier of entry (for me at least).
