Thank you a lot for your feedback! Controller support was also something I had thought about, but I was more focused on making a polished game that you could have fun with by using a regular keyboard and mouse; when I had some time left I was exhausted so I preferred fixing some visual bugs. While testing, I've also encountered scenarios where I had to go look for the aliens, so if I'd ever get back to this game to improve it, I'll definitely add some indicators and add a good pathfinding to the aliens, I might make a multiplayer tower defense out of this ^-^
