Decent, however I'd agree with the general feedback that the overlords are too slow/dumb and that the creeps should stop coming in between rounds so that the player has time to adjust and make necessary upgrades. I'd say it's a 3 out of 5, it's a good design and a good effort but the game play is still a little rough. Best of luck :3
Getting the badge by putting it on nightmare and following instructions ruins the game. The game is fun so just play normal and see how far you can get that's why it's here. Plus me if you agree =)
