Not sure what the goal of the game is, I built one turret on a planet and then it just kept shooting enemies in one shot and I couldn't figure out how to buy stuff for other planets

the music had me bopping my head!

Very confused

The UI for adding buildings on planets is too small to read or even click. I tried on multiple browsers but the result was the same.

To add to what Iggyminious said, you actually don’t have to build any buildings, since there is no win condition as far as I can tell, you can spam click green connections between planets and make a lot of money.

My main issue with this game is that it's overall too easy since I could build up enough turrets so quickly that the ships never posed any threat. The idea of expanding through space and managing different planets is an interesting hook and the presentation is mostly solid (the turrets all firing at once did get pretty loud though); I just think it needs to be balanced better.
