OK. I was finally able to download the game (funny that the itch.io client app wouldn't download it but I could download it from the itch.io website in my browser)
So I apologize to the developer again. The game is not too darkand it is very professionally done in the gameplay and pixel art. But I would like a bit more contrast between the units and the background.
One thing I would like to see added is an option to turn off mouse pointer edge scroll. The WASD keys are enough.
I deleted my original post because it was inaccurate and misleading for anybody interested in this good game.
