I like the idea of having a tower defence game where you’re moving towards a target. I didn’t make it too the moon unfortunately, like someone else said it would have been nice to see my progress towards it and I wasn’t sure how long I would be going.
I also think it would be nice if the upgrade menu stayed open when you click it as when I bought a new turret in the later stages I had to open the menu around 15+ times to get all the cheap upgrades for them.
