Ty for your comments. This is more of a prototype. If I have the time I would make a whole planet with varied enemies like super stardust hd. And randomized enemies like no mans sky. I could make the angle changable but I tought this gave it more a retro feel.
I played and reviewed your game too. I liked it, I like horde games. It has nice music and enemy type that reminds me of starship stroopers. Maybe it would be cool if it had more varied enemies. For example some that can fly. And towers you can buy that help in defence. And maybe things like spikes you have in gears of war.
