Got some solid bones here! The game (or its page) really needs a description for the controls somewhere readily available, it took me a failed run to realize I could zoom out and pan the camera. Another thing I would do is give the buildings descriptions; dropping into the game with no knowledge of what's happening and an impending wave of enemies was not very conducive to survivability. Also does gas do anything? Another aspect I think could use polish is the part where you can't build too far away from your base; there aren't any generic buildings to fill space with to extend easily, so I was alternating between rock and crystal miners, even though they really didn't serve a purpose

Reminds me of Mindustry as well. But I think the game needs a tutorial or an explanation of what each building does and also a clear objective for the game
